The garlic gives this shrimp dish fabulous flavor, and we always add an extra clove or a dash garlic powder to intensify that flavor. If you don't have fresh garlic, add about 1/4 teaspoon of a good quality garlic powder when you add the parsley. Serve the dish with sliced fresh vegetables or a tossed salad, or steam some broccoli or green beans. The recipe calls for clam broth, but it would still be delicious with more chicken broth or a cup of vegetable broth.
