I'm not going to suggest how you could screw up peanut butter, lest you think it's an assignment. Let's just say that the first time I used dried chilis in something, I didn't get the right order of magnitude.

But I've discovered that kitchen timers are my friends. Elizabeth doesn't understand why I set a timer when the bread machine starts (we pull the dough hook out at the end of kneading), because she'll pay attention when the kneading stops. I won't. I could be standing right next to the thing and completely miss it. So I set a timer, and when it bugs me, I figure out what I need to do.
