This is a sauce that my friend Karen taught me how to cook. It's lovely with shrimp, chicken, or scallops, but it's critical to cook the meat separately from the sauce and them combine it at the last moment. My family will turn themselves inside out to help peel shrimp if I even mention this dish, so I'm always willing to make it. The tomatoes are important in this dish and I would never substitute canned. I don't make this if the tomatoes aren't great. If you choose not to use the Tuaca (or apple brandy), substitute with apple juice concentrate. Serve it over rice for a perfect meal.
