ok, Paul Prudhomme said roast dried anchos for 15 minutes, while the Border cookbook said 5 minutes, and the temperature for both was 300 degrees. When I did the Prudhomme method the anchos got quite crispy and ballooned out, while the Border method they just got warm and not very crispy. Now maybe both recipes wanted a different consistency, but in both cases it was for a home-made chili powder. What is your preferred method? Length of time , temperature etc. I want to experiment I guess.
