Another reason to do "mise en place" is so you know that you have all the ingredients. No surprise that the yogourt is furry
or you're out of something you were sure you plenty of.
There's only two of us here too. Some of the same dishwasher annoyances. However, we have a small (`2/3 size), portable dishwasher, so we can usually fill it every day. BTW, I wouldn't buy a small one again. It doesn't really fit pots and pans well.
I hand wash my stainless steel frying pan because it doesn't get clean enough in the dishwasher, even on the "pots and pans" cycle. It used to get clean in the dishwasher before they took the environmentally nasty stuff out of the dishwasher detergents.
I really should get more in the habit of doing mise-en-place. It goes so much smoother when I do. It does turn into a bit of a circus when I don't.
