Use your favorite sweetener: honey, unrefined cane sugar, agave, barley malt, etc. (A light drizzle-about 1/2 teaspoon of real maple syrup tasted good in this!) It is very important to be certain the sunflower seeds you use for this recipe are fresh. If not, the butter will taste "off"-rancid. To store, use a covered container and refrigerate.
