One of the odder things about Mexico City is that you sometimes have to hunt for hand-made tortillas, apart from those you get at a decent restaurant when dining.
You can usually find somebody selling them at the various weekly tianguis set up around town. And at places like the Mercado San Juan.
But the best I've found so far is a place waaaay down south where you can buy them hot off the comal for about 15 pesos a kilo. It's up in Ajusco territory at the corner of Yobain and Tepekan. Check a map before trying to find it. It's alongside a Michoacana ice cream shop and it faces a vacant lot. If you go looking for it, consult a map. The best thing to do is go west off Picacho-Ajusco around Hokoba or Concal and go west to Yobain, then head south of the hill from there.
Anybody know of other places that sell hot hand-made tortillas, outside of restaurants?
