the first ingredient in this recipe is: 1 cup whole wheat bread, I am wondering if you meant to say 1 c of whole wheat flour.

When you see a confusing or contradictory set of instructions on the Internet, the first thing to do is to see if they were posted elsewhere. This advice is not specific to Food52 or just food recipes, it is applicable to all types of tutorials: arts & crafts, auto repair, Linux system administration, you name it.

It took me ten seconds to locate this recipe on the author's abandoned blog:

https://tastyd.blogspot.com/search?q=jalapeno

where the ingredient is properly listed as whole wheat flour.

Best of luck.
