Teachers receive lots of food gifts, but few complain. The gift of specialty food items -- whether they're purchased or homemade -- is a time-honored way to show appreciation. Although a box of chocolates, a fruit basket, mail order desserts and gourmet coffee blends are good choices, where food is concerned, it's always best to know a teacher's preferences beforehand. If your favorite teacher is a tea drinker, the best South American coffee blend will be a bit of a letdown no matter how rare it is. Health and diet issues can be important considerations, too. Food allergies or a steely determination to lose those last five baby pounds may keep your favorite teacher from enjoying the bounty, so be sure to do some checking before you bake or shop.
