Why This Recipe Works

Making a deeply flavored tomato soup is hard enough on the stovetop, but getting the consistency right in a slow cooker seemed daunting at best. First, there was the issue of the tomatoes (fresh or canned?), and second, the matter of technique (how to add flavor and texture to the soup). Since perfectly ripe tomatoes are available just a few weeks a year, we turned to our trusty standby, canned diced tomatoes, which are always available and prep-free. As for technique, we started by building an aromatic base by microwaving onion and other aromatic ingredients. To add richness, we incorporated heavy cream and dry sherry after the soup was pureed.
