Mise en place
When I got married, I started reading cookbooks. One term that kept popping up everywhere was mise en place, a French expression that means to get all your materials together before you start cooking.
Cooking is so much more fun and relaxing when I have all my ingredients and materials in place before I start. I don't have to discover halfway through that I'm out of something, or that Tiger Lily has carried off the potato masher to the backyard. I can just cook, and I like that.
Another thing that helps me enjoy cooking is to start with a clean kitchen. I made a cake on Friday, starting with a clean kitchen (and even an empty dishwasher!), and it was so rewarding to start with a blank slate, make up the cake, and then have my kitchen back to blank-slate condition within five minutes after the cake was in the oven.
