Although she lived in a different era, my grandmother's efficient strategy of cooking makes a lot of sense today. Like her, I'm never without a supply of tomato sauce. It takes less than an hour to whip up a new batch, so it's easy to make more when I run low. The sauce goes into my soups and stews, it becomes a braising liquid for meats and, with a few added ingredients, it can turn into any of several richly flavored pasta sauces. I use my tomato sauce in place of canned tomatoes, and since it's already seasoned and reduced, it saves time during cooking. In short, my stash of frozen tomato sauce lets me put delicious homemade meals on the dinner table faster since I don't have to start from scratch every time.
