Dried herbs: Dried herbs (besides the parsley) can be used in place of fresh, but the flavor will be sharper. Thanksgiving butter made with dried herbs is best used for basting or placing under the skin of chicken or turkey before roasting. Use 1/4 teaspoon dried sage, 1/8 teaspoon dried thyme, and 1/8 teaspoon dried rosemary in place of the fresh herbs.
Using salted butter: Salted butter can be substituted for the unsalted; just omit the kosher salt.
Storage: Thanksgiving butter can be refrigerated in an airtight container or rolled up in plastic wrap for up to 5 days or frozen for up to 2 months. Let thaw overnight in the refrigerator before using.
