Botana de PapitasBite-size red potatoes are available in most of Mexico's public food markets, but small 2-ounce red potatoes are easier to find here, so that's what I used for this recipe. Each potato is cut in half, baked, and stuffed—which can be done ahead. A final finish under a hot broiler to melt the cheese takes only a few minutes. Buy potatoes that are uniform in size and shape.
