I was just in lovely Puebla. I've never been and it was a gas. I met some wonderful people and the food was incredible.
I brought back a sack of chiles called Navideño, which are a smoked red chile, like guajillo. The interesting thing is you can tell it's a wood smoke. It's absolutely delicious. I haven't had much time to play with them but I made a quick sauce with one of the chiles, a little tomato and some oregano.
