Lime powder can be used for a tropical lime taste on fish, poultry and vegetable dishes or desserts. Just a half teaspoon flavors one pound of mix for cakes, pastries, dessert fillings or frostings. Try mixing with powdered sugar and sprinkle on pastries or desserts or mix 1/4 teaspoon with bottled Italian dressing and baste fish or poultry while grilling or baking.
