unbleached lecithin 1/4 tsp. citric acid Cover prunes with water and bring to a boil. Cool. Blend prunes, water, lecithin, and citric acid in blender until smooth. Pour in clean quart jar and refrigerate. Keeps up to 30 days. I pour mine into old jelly jars and freeze them. I use 1:1 amounts when substituting for oleo in recipes.
