There are two methods for Freezer Doughs:
First, you can mix, knead, and shape the dough into a disk. Instead of
letting dough rise, wrap the disk airtight and freeze. Thaw dough in
the refrigerator, in the microwave oven, or at room temperature; then
shape, let rise, and bake.
Or you can freeze the dough after shaping. Thaw it in the refrigerator
or at room temperature, let it rise, and then bake.
