Martin’s mother, our kids’ grandmother or abuelita (in Spanish) gave us this recipe.
She’s from the city of Aguascalientes in Mexico.
There aren’t exact measurements, but the captioning gives you all the important keys to recreating her recipe.

To honor Martin’s mother, we decided to make this video more relaxed and peaceful, without a voiceover.
