Now why didn't I think of that? According to Rick Bayless's site, dried NM chiles weigh about
1/3 oz, so that would be two ounces or 1/2 cup as my 1/2 cup jars of cayenne, etc from Penzeys are 2-2.5 oz. That's a lot of chile powder. Am I figuring this right? My aged brain is swimming.
I know I get more than a teaspoon from pulverizing a small chipotle. I used to have a chart of chile powder/peppers equivalents but have misplaced it. I keep the dried ones on hand now, buried in the bottom back of the freezer.
