May I Can Pumpkin Butter?

Canning pumpkin butter or mashed or pureed pumpkin is NOT recommended.

Home canning is not recommended for pumpkin butter or any mashed or pureed pumpkin or winter squash. Pumpkin is a low acid vegetable and requires special attention to preparation and processing.

While pumpkin butters and pumpkin preserves are popular, they cannot be safely canned for room temperature storage.

Freeze pumpkin puree and pumpkin butter instead.

To freeze pumpkin puree.
Select full-colored mature pumpkin with fine texture. Wash, cut into cooking-size sections and remove seeds. Cook until soft in boiling water, in steam, in a pressure cooker, or in an oven. When soft, remove pulp from rind and mash. To cool, place pan containing pumpkin in cold water and stir occasionally. Pack into rigid containers leaving ½-inch headspace, and freeze.
