I cooked again tonight--my most successful venture yet. I used this recipe for red curry with shrimp, sweet potato, and mango from Nigella Lawson's express cookbook, and it was really really tasty. It ended up way too hot, due, I guess, to the type of curry paste I bought, but it was still good, and I'll definitely make it again, with half as much curry paste.
I also spent all afternoon cleaning our house to make it more presentable and pleasant. Look at me working on my resolutions!
