Go easy on the chocolates. It may be a romantic gesture to shower your date with candy hearts and chocolates, but the results can kill the mood. Too much sugar can spike and then drop your blood sugar levels, so that you get tired very quickly. Remember that it's all about focus, and plowing through a bag of candy doesn't help you do so.
Do it together. (The cooking, that is.) Remembering that it's all about the ritual and senses, prepare your Valentine's Day meal together. "When you're with someone you love, get in the kitchen with them," says Goudreau. "You're testing the food together; you're stirring the batter … That can be really sensual."
