Care and Storage
Glass jars are dishwasher safe. Hand washing is recommended for the lids to help preserve their finish and sealing components.
For freezing, use only jars approved for freezer storage, leave adequate headspace for expansion, and thaw gradually in the refrigerator. Avoid sudden temperature changes.
For home canning, confirm that the jars are approved for the intended processing method and use appropriate two-piece Mason canning lids with tested canning instructions. Standard one-piece plastisol-lined lids should not be assumed suitable for home canning.
