Cook one meal from a different country every month. I've always loved cooking and I have a partner who is equally as enthusiastic to eat it with me! The foods have to be something I've never cooked before. Some can be ones I've eaten before, so I have something to compare to. I'm thinking of starting with traditional foods from Afghanistan, Russia, Ethiopia, Mongolia, Myanmar, Uyghur...
Absolutely no digging in to the tub of butter, and no other food bits (usually bread crumbs) must be left inside.
If dug in to, it must be smoothed out before putting back in to the fridge. As for the crumbs, take them out and put them back on to the bread they came from. Now the butter can be put back in to the fridge.
