Whenever I'm feeling really stressed out, I force myself to set aside the time to make a risotto. It forces me to concentrate on something that takes patience over a period of time much longer than what it takes to cook most dishes. The bulk of it is spent gradually adding a broth/wine mixture to rice while constantly stirring it. Focusing on it is almost meditative, giving me a chance to reconnect with concrete things that are going on around me and to calm down.
Then, after it's finished, I get to eat it and (more often than not) it's amazing. The subtlety of a good risotto borders on the sublime.
