Step 1

Break up the pieces of bread if you haven't already and toss them into the food processor bowl. You don't even have to defrost the bread if it's frozen before whirring it up most of the time (the exception is a hard crust from artisan bread).

Step 2

Whir the pieces until finely and evenly chopped.

Step 3

Store in a glass mason jar or other container in the fridge for a month or in the freezer for 6 months or more.
