If you love yogurt so much that you restock on every visit to the store, consider this: You can cut your grocery costs by skipping the store-bought yogurt varieties and learning to make your own. People have been making homemade yogurt for hundreds, if not thousands of years. There are many methods of doing so that require nothing more than the cookware and utensils already in your kitchen. True, a yogurt maker simplifies the process but only to a limited degree. Unless you plan on preparing heaping quantities of yogurt on a regular, continuing basis, there's no reason to buy such a specialized appliance, especially when you factor in the bulky, difficult-to-store size of the average unit.
