Tacos de Bistek, Nopales, y CebollasWhen we went to view the ruins of Cacaxtla in the tiny state of Tlaxcala only a few miles from Puebla, we were invited to a home to watch amaranth candy being made. Amaranth, a plant with edible leaves and seeds, is grown in the area. The seeds are ground to use like flour, or toasted and mixed with honey for candy. While we were there, we were treated to a snack of the special regional tacos made with blue corn tortillas. The thin steaks, cactus, and onions were quickly cooked on a hot griddle and stuffed into fresh blue corn tortillas. Green salsa and cold beer accompanied the tacos. White corn tortillas can be used in place of blue corn tortillas.
