“Palanquetas with peanuts are very popular in Veracruz, where I grew up,” says Gonzalo Guzmán, now the chef and co-owner of Nopalito in San Francisco. As a boy, Guzmán sold them at local fairs, cut into portions and wrapped in plastic. You can substitute either pumpkin or sesame seeds for some of the peanuts, if you prefer. “In Mexico, they would transfer the mixture from big pots into rectangular molds, then flatten the candy using an iron,” he says, but you can use a cake pan—or even your hands—to shape them. Wait until the candy is mostly, but not fully, cooled before cutting in.
