Suddenly I remembered how, growing up, whenever there was a celebration, there were gelatinas alongside the cakes on our dessert tables. And like that, I found myself with a long list of different cake and gelatina recipes—and not enough space to include them all. Gelatinas are inexpensive to make, often requiring just a handful of ingredients that you probably already have in your pantry: unflavored gelatin, milk, sugar or condensed milk, and fresh fruit.

After I finished stuffing my face with a hot tamal de pollo, I’d buy a little cup filled with gelatina de mosaico.
