Pears can be frozen. How they should be frozen depends on their intended use. Pears can be frozen dry or with sugar if they are going to be used to make pies or with a syrup pack if they are going to be used to make uncooked desserts.
When frozen with sugar or a syrup pack, pears are less likely to brown or get freezer burn. They should be washed, peeled, cored and sliced before freezing, and any brown spots should be removed.
Pears will last many months in the freezer. They should be stored in airtight, freezer-safe plastic containers or bags.
