Guacamole in Aztec means avocado (from ‘guac’) sauce (from mole). If you can make a corn tortilla, says Tommi Miers, you can make tacos, tostadas, tacquitos, with their citrussy-fresh fillings and their hot salsas. Learn to char your chillies, grill your tomatoes, toast your garlic, and pat out your own corn tortillas like (as one Mexican proverb has it) ‘a butterfly’. Join Tommi at the chic Miele Gallery to make and eat classic Mexican street food as they do in the markets of Mexico.
