Seared tuna steaks

One good way to cook a tuna steak is to heat a cast iron pan up really hot, until the bottom looks like it's coated with white ash. Throw in some oil (be wearing a heavy apron, and it doesn't hurt if you wear glasses, just in case of oil spatters); throw on a tuna steak (gently - again, oil splashes) that you've covered in freshly ground pepper and bits of lemon peel. Let it sear, flip it, let it sear, and then flip again and let it cook.

One bad way to realize you're forced to cook tuna steak this way is to forget you've started pre-heating the pan while you pull your morning espresso... in your underwear.

(No serious damage - some oil spatters on my thigh. And I wasn't prepared to deal with a smokey kitchen.)
