|Blackberries||1 Cup (16 tbs)|
Place fresh or thawed whole frozen blackberries in food mill, blender, or food processor and process until smooth. If desired, seeds may be removed by straining through a medium sieve and using a rubber spatula to press pulp through while scraping underside of sieve. Add sugar to taste. A good rule of thumb for sweetening is about 2 tablespoons sugar per cup of whole berries.
