Blend the sugar with cellulose gum to disperse it evenly so it doesn't clump when hydrated. Set aside.
In a medium sauce pan: combine heavy cream, Mexican crema, milk, salt, and blended sugar. Whisk well, then mix in the corn.
Bring to a simmer over low heat for 10 minutes, then mix in vanilla while it's cooling.
Once cooled down, pour the mixture into a blender and blend until smooth.
Push the mixture through a fine-mesh sieve to remove any remaining corn solids.
Taste the mixture and adjust the sweetness if needed.
Pour the mixture half way up into your popsicle mold, then drizzle some cajeta on top. Repeat once more. Insert popsicle sticks and freeze for at least 8 hours.
To release the paletas, slide a popsicle stick down the sides to loosen them. Or, place the mold in warm water for 20 seconds.
Notes
Substitutions: Please see the FAQ section if you need substitutions for cajeta, cellulose gum, or Mexican crema!Use canned corn for maximum flavor: Canned corn gives a stronger, more consistent corn flavor than fresh when it comes to flavoring desserts. It's also more convenient!Adjusting sweetness: The corn mixture should not be that sweet, since we are adding cajeta. However, keep in mind that desserts lose some sweetness once frozen. Adjust accordingly.Chill before freezing: If you're using cajeta and want it swirled throughout evenly, refrigerate the final mixture before pouring into molds. This helps the cajeta stay evenly distributed, preventing it from sinking to the bottom.Store properly: Keep your popsicles in an airtight container or wrap them individually to avoid freezer burn. They’ll stay fresh in the freezer for up to 1 month.
