Citrus seasoned dressing & sauce. Ponzu is a seasoned Japanese soy sauce, accented with citrus. It has the perfect balance of salty, tangy and sweet to enhance the flavors of broiled meats, poultry, seafood or vegetables. Or, use ponzu as a sauce for sushi, sashimi, cubes of tofu or raw oysters. Instead of the usual cocktail sauce, dip cooked jumbo prawns in ponzu. Add a small amount of vegetable oil to ponzu for a dressing over greens or use to season a mixture of meats, vegetables and pasta to make a quick main dish salad.
