You can make this butter during the growing season, then freeze it to enjoy the taste of fresh basil all year long. It can be used to enhance the flavor of vegetables, chicken, bread, or fish. I found this recipe on AllRecipes.
In a food processor, chop basil. Add butter, lemon juice and pepper and garlic salt; blend until smooth. Drop by half-tablespoons onto a baking sheet; freeze. Remove from baking sheet and store in freezer bags. Use to flavor chicken, fish or vegetables.
