Preheat the griddle or skillet. Lightly butter the hot griddle before each batch of pancakes. Pour out the batter to make four-inch rounds. Quickly drop about six to eight frozen berries onto each pancake. Test for doneness by lifting a corner of a pancake with a metal spatula. When golden brown, turn over and cook about 30 seconds on the other side. Serve with warmed maple syrup, hickory bacon, sausages or scrapple.
