Michigan Fresh: Using, Storing, and Preserving Cauliflower (HNI20)
Cauliflower can be preserved and served in many way. Michigan-grown cauliflower is available July through October.
Early Snowball, Snow Crown, Self-Blanche and Snow King hybrid are excellent for fresh use or freezing. Recommended purple cauliflower varieties for fresh use and freezing are Purple Head, Early Purple Head and Royal Purple. Early White hybrid is a good choice for pickling.
Storage and food safety
- Wash cauliflower in cool running water. Do not use soap.
- Keep cauliflower away from raw meat and meat juices to prevent cross-contamination.
- For best quality and to preserve nutritional quality, preserve only what your family can consume in one year.
|1 1/3 pounds||= 1 pint frozen|
|Two medium heads||= 3 pints frozen|
|12 cups flowerets||= 9 half-pints pickled|
|1 bushel (12 pounds)||= 8-12 pints frozen|
How to preserve
Cauliflower usually discolors and grows stronger in flavor when canned. For this reason, canning is not recommended.
Choose compact heads. Trim off leaves and cut each head into pieces about 1 inch across. If necessary to remove insects, soak for 30 minutes in a solution of salt and water (4 teaspoons salt per 1 gallon water). Drain. Water blanch for 3 minutes in water containing 4 teaspoons salt per 1 gallon water. Cool promptly, drain and pack into airtight freezer containers, leaving no head space. Seal, label, date and freeze. Use frozen cauliflower within 8 to 12 months for best quality.
Alternatively, freeze individual flowerets on cookie sheets or trays, transfer frozen flowerets to freezer bags, remove air, seal, label and freeze.
