- When possible, preserve fresh, locally-grown cabbage for the best quality and nutritional value.
- Know when fresh cabbage is available in your state with this seasonal food guide.
- Select firm, compact heads. Do not use cabbage that show signs of decay or mold.
- Use 2 ½ - 3 lbs cabbage per quart container
- Ice (approx. 1 pound/pound vegetables)
- Large cooking pot with lid
- Blanching basket/strainer/slotted spoon
- Cutting board
- Use clean packing containers and materials that are moisture and vapor-proof/resistant:
- Rigid containers (glass jars and hard plastic containers) are especially good for freezing foods with liquid. Covers for rigid containers should fit tightly.
- Square or rectangular, straight-sided rigid plastic containers make the best use of freezer space.
- Wide-mouth, dual-purpose glass jars made for canning and freezing are tempered to withstand extremes in temperature and allow for easier removal of partially-thawed foods.
- Narrow-mouth dual-purpose glass jars can also be used but require greater headspace (to avoid expansion breakage at the shoulder) and foods must be completely thawed before removal.
- Flexible bags or wrappings (plastic freezer bags, freezer paper or wrap, and heavyweight aluminum foil) are best for freezing food products with little or no liquid.
- Vacuum packaging removes more oxygen than other freezing methods (Refer to manufacturer's instructions.)
3. Prepare Equipment
- Before use, wash containers in hot soapy water and rinse well. Dry.
4. Prepare Vegetables
- Thoroughly wash cabbage.
- Remove coarse outer leaves, trim if desired.
- Cut heads into medium or coarse shreds, thin wedges or separate into leaves.
- Blanch in boiling water for amount of time indicated in table below.
- Use one gallon water per pound of prepared cabbage.
- Lower cabbage into vigorously boiling water. Place a lid on the pot.
- Start timing as soon as vegetables are in boiling water.
- Cool in ice water. Drain well.
- NOTE: Cooling should take the same amount of time as blanching.

- Label with the name of food, date, and type of pack.
- Freeze as quickly as possible to 0°F or below.
- For quickest freezing, place containers in single layers in freezer.
