PRESERVING GUIDE

Preserving Cauliflower (summer/autumn)

Make the most of your cauliflower (summer/autumn) harvest with careful short term storage and preparation.

Cauliflower florets arranged on a tray for freezing

Freezing Cauliflower (Summer/Autumn)

General preservation or storage guidance

Preparation About 30 minutes active, plus cooling and freezing

Compact cauliflower florets freeze well after a short salted-water blanch and rapid cooling; frozen florets are best used cooked.

Method

  1. Choose a compact, white summer/autumn cauliflower. Remove the leaves and thick stalk, then divide the curd into florets about 2.5 cm (1 in) across.
  2. If insects are present, soak the florets for 30 minutes in 4 tsp salt per 1 US gallon (about 3.8 litres) water, then rinse and drain.
  3. Blanch florets for 3 minutes in boiling water containing 4 tsp salt per gallon. Work in small batches and start timing when the water returns to the boil.
  4. Cool promptly in cold water and drain very well. Pack into freezer containers or bags, press out excess air and seal.
  5. Label and freeze promptly. Use in cooked dishes; thawed cauliflower softens. Keep continuously frozen and thaw only what is needed.

Storage

Freezer at −18°C or colder · Keep continuously frozen; no exact quality period stated

Cauliflower florets preserved in a glass jar

Pickling Cauliflower (Summer/Autumn)

General preservation or storage guidance

Preparation About 1½ hours active, plus jar processing and cooling

This tested cauliflower pickle uses a fixed 5% vinegar recipe and boiling-water process; use the stated floret size, brine ratio and processing time unchanged.

Method

  1. For about 9 half-pints, measure 12 US cups (about 2.8 litres) cauliflower florets cut 2.5–5 cm (1–2 in), 4 US cups (about 950 ml) white vinegar labelled 5% acidity, 2 US cups sugar, 2 cups thinly sliced onion, 1 cup diced sweet red pepper, 2 tbsp mustard seed, 1 tbsp celery seed, 1 tsp turmeric and 1 tsp hot red pepper flakes. Keep the source recipe’s proportions and jar sizes.
  2. Wash the florets, remove stems and blemished leaves. Boil them for 3 minutes in water containing 4 tsp pickling salt per US gallon; drain and cool.
  3. Combine the measured vinegar, sugar, onion, red pepper and spices in a saucepan. Bring to a boil and simmer for 5 minutes.
  4. Distribute onion and red pepper among clean hot jars. Add cauliflower and hot pickling liquid, leaving 1.3 cm (½ in) headspace.
  5. Process half-pint or pint jars in a boiling-water canner for 10 minutes below 305 m elevation, 15 minutes from 305–1,829 m, or 20 minutes above 1,829 m. Follow the complete source canner instructions; do not change vinegar strength, ratios or jar size.
  6. Cool undisturbed and check seals. Refrigerate any jar that did not seal and opened jars; discard jars with leakage, bulging or spoilage.

Storage

Store correctly sealed, processed jars in a cool, dark place; refrigerate after opening · Use the complete tested process; no additional period stated
