Being an anthropologist in a former life, every time I find a new-to-me fruit or vegetable, I look up its history and uses. Papaloquelite (or “papalo” for short) is native to Mexico and South America and is mainly used in salsas or as a garnish to tacos and other dishes. In Bolivia, it’s common to see vases of papalo on restaurant tables so that diners may pull off its leaves and season their food. For this recipe, papalo takes the place of cilantro in a quick and easy guacamole that is served atop sweet pepper and summer squash tacos.
