This is fun and can be a starter or a side.
Cook your potato cakes, as directed. Butter the pan you cooked them in and set it on medium. Slice the apples into ½ inch pieces and place them in the pan. While they sizzle, mix the sour cream and bacon jam. Spread a thin layer of the sauce onto each pancake. When the apple pieces are tender, take them off the heat. Lay a slice on each pancake, then spread more sauce on them. Repeat this step until you have several layers of apple and sauce on each potato pancake. Dig in.
