When cooking is something that has to get done for practical reasons, it can easily become a chore. Yet even when the chore is one that will take hours – such as making pasta for a crowd – if it’s shared by many hands, it becomes a pleasure. So this holiday season, whether you’re making pasta, pastry or sushi, let your friends, family or neighbors join you in the kitchen and you’ll find the time spent there to be among your most treasured memories. The edible gifts – they’re the bonus.
