Sopa de Letras para NiñosMexican children, like children around the world, are fascinated by miniature letters of the alphabet, in pasta form, floating in their soup. They take delight in naming the letters that appear in their spoons before popping them into their mouths. The small amount of cumin adds a subtle, special flavor but won't startle young taste buds. Alphabet pasta should be available in most grocery stores.
