If pears are ripe and soft - Core and diced. If pears are tougher you will need to par cook them by doing the following: place the diced pears in a medium saucepan. Fill the pan with water so that half the pears are covered. Cook over medium heat, bringing to a boil then simmering for about 5 minutes until the pears just start to turn semi-translucent. Drain very well.
