This birote salado recipe has been THREE YEARS in the making and I am so excited to share it with you!

Of every recipe I have published, I am most proud of this one. It holds a lot of sentimental value to me, because I learned how to make it just for my dad. Since I was a young girl, he has ALWAYS complained that you can’t find good birotes in the US. My dad was born in Guadalajara and tells me all the time how much he misses birotes, so I took it upon myself to learn how to make them!

Why You’ll Love This Recipe

If you’re like my dad and just want some decent birotes reminiscent of the delicious crusty rolls you can get in Guadalajara, you’ve come to the right place. These are as good as it gets when it comes to birote salado! Here’s why-

  • A lot of thought and care went into developing this recipe. It took me 3 years to get here because I needed to harness sourdough first, including making & maintaining a strong and healthy sourdough starter.
  • It is difficult to find birotes salados, even in areas that have large Mexican communities.
  • There are step-by-step photos for EVERY part of the process to ensure you don’t mess it up!
  • My father was my taste tester for every single recipe batch I developed. Every time I thought I got it right, he was truthful and told me it wasn’t there yet. That is until this batch! I finally got his stamp of approval, along with my Abuela and Tio. Now they all ask me to make birotes for them any time I see them!

Disclaimer: you can have all the right ingredients, measurements, techniques and instructions on how to make birotes exactly as they are made in Guadalajara, but they cannot be 100% replicated. This is because the microbiome, elevation, water and climate are significant & uncontrollable variables. I have done the best I can to recreate them as closely as possible, but please keep in mind that they will not be exactly the same!

What is Birote Salado?

Birote salado is a traditional and unique Mexican sourdough bread, originating from Guadalajara, Jalisco, where my family is from! It’s known for its distinctive crusty exterior and soft, fluffy interior. This bread is used for Tortas Ahogadas, a famous regional dish from Guadalajara (one of my all-time favorite dishes).

Many people would say that birotes are the Mexican version of a French baguette. It is made with wild yeast (sourdough starter) and rolled into a similar shape as a baguette, but shorter. Its unique texture and flavor are what set it apart from other breads! The sourdough starter is refreshed with lime juice, egg, beer, sugar, and a little salt. This is a pretty significant departure from how sourdough bread is traditionally made, which is why this beloved bread is so unique.

The History of Birote Salado

One thing that is known for sure, is that the history of birote salado dates back to the 19th century in Guadalajara, Jalisco. Its exact history in terms of who created it and why it’s called “birote” seems to be uncertain, but it is generally accepted that birotes are based on French recipes for baguettes.

Most of my research suggests that a Belgian volunteer in the French army named Camille Pirotte created birotes, while trying to teach the people of Guadalajara how to make French bread. He couldn’t find yeast, but the warm climate allowed him to make sourdough, resulting in what was originally called ‘pan de birote.’

None of this can be definitively confirmed, but I can totally see this being accurate because the word “birote” sounds very similar to the last name “Pirotte.” You can read more about this version of the origin of birotes here.

If you want to see how birotes are made in Mexican bakeries today, I recommend watching this YouTube video. It also shares a bit about its history. I watched it a million times trying to figure out how to make them, and my recipe is based off everything I was able to observe.

Ingredients for Birote Salado

– For the levain:

  • Sourdough starter- you will need an established sourdough starter to make this recipe. To make the levain, make sure your sourdough starter has already peaked and is starting to fall back down.
  • Beer- use any Mexican lager. Beer adds flavor complexity, and the carbonation introduces extra gas, creating a lighter & airier crumb.
  • Lime- a little lime juice helps give the birotes their signature sour flavor. It also aids in the fermentation process, encouraging growth of good bacteria while limiting excessive yeast activity, which balances the flavors. Lime juice can also aid in enhancing the shelf life.
  • Egg- improves structure, enriches the dough, and helps to achieve a nice golden color to the crust.
  • Sugar- sugar provides a fermentation boost, acting as a food source for the yeast. It also helps to balance the flavors of this salty bread, but it will not make it sweet.
  • Salt- I’m not 100% sure, but I believe salt was originally added to the levain to slow down the fermentation process since the climate was so warm. For tradition purposes, I am keeping the salt but adding only a tiny bit here.
  • Flour- I use Kirkland Organic AP Flour

– For the final dough:

  • All of the above levain
  • Flour- I’ve tried making it with both all-purpose flour (Kirkland Organic AP Flour) and bread flour (King Arthur Bread Flour). Either one will work fine, or even a 50/50 mix of the two, but I preferred batches made with bread flour and so did my family.
  • Water- I only use RO water (reverse osmosis water) for sourdough baking, not because it is the best but because it’s what I have that works for me. Refrain from using tap water as it might have minerals that prevent proper fermentation. Spring water is probably the best option if you don’t have RO water.

Summary of Hydration:

Most people don’t really need to know any of this, but if you’re a sourdough baker I figured you might be curious about the hydration levels so here they are:

  • Sourdough starter: 100%
  • Levain: 93.75%
  • Final dough: 76.4%

Before you start making this recipe

I would like to preface this by saying that this is not a beginner recipe. There is a reason it took me such a long time to develop this recipe- it was hard af! The difficulty of this recipe is 2-fold:

  1. You should have a good understanding of sourdough already, especially the bulk fermentation process. This is what took me the longest to harness, and it takes a lot of hands-on practice! I wrote the recipe with beginners in mind, so I hope it is easy to follow regardless of difficulty level.
  2. The baking process is a little complicated, but necessary for a good oven-spring and pronounced belly/ear. I struggled a lot with this part because I just couldn’t get my birotes to open up. It requires a lot of extra work, but I literally tried EVERYTHING before getting to this solution!

The ambient temperature and the temperature of my dough for this recipe are around 78°F. I have provided time stamps throughout the recipe as a guideline to help beginners based on this temperature. You can use time as a rough guideline for the completion of bulk fermentation, but it’s not a reliable indicator on its own.

Ingredients 

Wake up feed (if needed)

  • 20 g sourdough starter
  • 40 g all-purpose flour, Kirkland Organic AP Flour
  • 40 g water

Levain

  • 80 g sourdough starter, just passed its peak
  • 80 g all-purpose flour, Kirkland Organic AP Flour
  • 40 g Mexican lager beer
  • 30 g egg, whisked, about half an egg
  • 10 g lime juice
  • 8 g sugar
  • 1 g salt

Final Dough

  • all of the above levain, about 250 g
  • 400 g King Arthur Bread Flour, or Kirkland Organic AP Flour
  • 285 g water
  • 10 g salt

Instructions 

Wake up feed (if needed)

  • The night before you plan to bake (at least 8 hours before), feed your sourdough starter. Begin with 20g of unfed sourdough starter, then add 40g each of water and all-purpose flour. I use Kirkland Organic AP Flour.
    *You do not need to do a wake up feed if you feed your starter daily at room temperature and you have 80 grams of starter you can use. You can skip straight to the next step, even if your starter has passed its peak, and has fallen quite a bit. Just keep in mind that you will need a total of 80 grams of sourdough starter.

Levain 8AM

  • Add all of the levain ingredients to a measuring glass or jar and mix until fully combined. Make sure you use a jar large enough to allow the levain to double in height. Loosely cover with a damp towel or plastic wrap.
    At temps between 76-78 degrees Fahrenheit, it should take about 4 hours to double. If it is really cold in your house, put the jar in your oven with the light turned on.

Final dough 12PM (begin bulk fermentation)

  • Once the levain has doubled in size (about 4 hours), scrape all of it into a mixing bowl and mix with 285g water. Then add 400g of flour and combine to form a shaggy dough, making sure there are no dry spots of flour left. Cover with a damp towel and let it rest for 30 minutes.

  • After 30 minutes, sprinkle half of the salt evenly over the dough, wet your hands, then do 4 stretch and folds. After the 4th stretch and fold, sprinkle the rest of the salt over the dough and repeat stretch and folds until the salt is evenly distributed. Cover and rest for 30 minutes.
    *How to do stretch and folds: gently slide your hand under one side of the dough, then lift it up and stretch it as far as it comfortably goes without tearing. Fold the stretched piece over the top of the dough, effectively folding it in half. Rotate the bowl a quarter turn, and repeat the stretch and fold on the next side. You’ll stretch and fold each of the four “sides” of the dough (like an envelope fold).
    Collage of six images showing hands performing stretch and folds in a clear glass bowl. The sequence captures the process of stretching and folding the dough.
  • After 30 minutes, do one set of coil folds with wet hands. Then cover and rest for 30 minutes.
    *How to do coil folds: Slide your hands under the dough from both sides, supporting it as you gently lift it up from the center. Let the weight of the dough pull it down naturally. Coil or tuck one end of the dough underneath itself, folding it toward the center. Do the same with the other end, folding it over the first fold and creating a “coil” structure in the dough. Rotate the bowl and repeat.

  • Do three more sets of coil folds, covering and resting for 30 minutes between each set. By the time you do your last set, the dough should feel and look much more plump, airy, and smooth. Cover and continue to bulk ferment to 75% rise (done in about 1 hour after last coil fold).
    *this recipe is meant to be baked on the same day. If you prefer to cold-proof overnight and bake in the morning, see my notes in step 2 of final shape & proof section.

  • A more reliable way to check if your bulk fermentation is complete, is to look at the dough. It should have increased in size, by about 75%. There should be bubbles forming at the top, sides, and bottom of the dough. The outer part of the dough touching the sides of the bowl should also be domed, and pull away from the sides easily.

Divide, preshape, & bench rest 3:30PM

  • Lightly flour your work surface and gently turn the dough out from the bowl. Using a bench scraper, divide the dough into 4 pieces. Pull the edges of the dough into the center to create tension, then flip it over seam side down and use the push & pull method to roll into a ball. Cover with a damp towel and rest for 20 minutes.

Final shape & proof 3:50PM

  • Lightly flour your work surface again, then gently flatten the dough (but not too much) and roll the dough into itself, creating tension as you roll. Pinch the seam together, then roll into a tapered tube shape. Flouring the surface again after pinching the seams will help it roll smoothly without sticking.

  • Transfer the rolled out dough onto a floured baker's couche (or tea towel), seam side up. Fold up the sides of the linen to give the dough some side support. Cover with a damp towel and proof at room temperature for 30 minutes to 1 hour.
    *If you prefer to bake in the morning, you can cold proof these in the fridge overnight, but that is not how it is traditionally made. If you choose to cold proof, it is best to bulk ferment to 30% rise instead of 75% rise, which will take less time and probably require one less set of coil folds.

Oven preheat & setup

  • Meanwhile, preheat your oven to 450 degrees F. While it is preheating, place a baking steel on the top rack. The bottom rack should be positioned on the lowest level, and the top rack should be positioned two levels above (refer to photo).
    If you have some, I highly recommend putting some lava rocks in a cast iron skillet on the bottom of the oven. If you don't have lava rocks, just a cast iron skillet is fine.
    The image shows an open oven with a baking steel on the top rack and a cast iron pan on the bottom of the oven.
  • Roll up 3 kitchen towels and put them in an oven-safe vessel. I'm using a cheap stainless steel pie pan (don't use something you care about- it will get ruined). Saturate the towels in boiling hot water.

  • Prepare another cup of boiling hot water and set it aside for now.
  • Place the saturated towels on the bottom of the oven, right next to the lava rocks. The lava rocks are for the initial burst of steam, and the towels are for continuous steam. Refer to the photo below for the final setup.
    I also recommend locating the vents (mine is behind the stove grates) and blocking them with damp tea towels.

Prep & score dough

  • Transfer the birotes from the bakers couche to an inverted baking sheet with parchment paper. I use a transfer peel for this. If using your hands, careful not to deflate or disrupt the shape of the dough too much.
    Four uncooked, elongated dough pieces rest on a parchment-lined inverted baking sheet. The dough appears proofed and is arranged in a neat row, ready for baking.
  • Score the birotes about half an inch deep, straight down the middle.

Bake (between 4:20 and 4:50PM)

  • Open the preheated oven, place a dry towel on the oven door (to prevent it from shattering if any water touches it), then slide the birotes onto the baking steel and put the baking sheet on the bottom rack, right underneath the birotes so that the bottom doesn't burn.

  • Turn the oven OFF, then quickly & safely pour the remaining cup of boiling hot water onto the lava rocks, remove the towel and shut the door. Be very careful- do not put your face too close to the oven because there will be a huge burst of steam!
    *I use the "oven off" method for this recipe because I have a gas oven, and this is the ONLY technique that worked for me. This method allows for maximum oven spring, resulting in a beautiful belly and pronounced ear.
  • Bake with the oven turned OFF for 15 minutes. After 15 minutes, remove the steam towels from the bottom, and spread the birotes out just a bit more so the sides bake evenly in case they are too close to each other. Turn the oven back on to 425 degrees F for 15-20 minutes, or until the crust is a nice golden brown color.
  • The birotes are ready once they have reached an internal temperature of 205 degrees F and are a nice golden brown color on the outside. Rest on a cooling rack for at least 20 minutes to allow the crumb to fully set.
