I get a little annoyed by recipes. Why? Because everyone writes recipes like they invented the idea of making yeast rise or making egg whites froth or making water boil. No one ever explains why they’re telling you to do the things they’re telling you to do. If they did you’d be able to embellish upon the recipe indefinitely, and then it’s not their recipe anymore. Guess what? I want you to make frittatas with whatever ingredients you want. I’ll tell you what I put in there, and then I’ll tell you what the real flesh and bones of the procedure are, and then you can make them your own. Deal?
