Red and green chilli pieces prepared for freezing on a tray

Freezing Chilli

General preservation or storage guidance

Preparation About 15 minutes active, plus freezing

Whole or sliced chillies can be frozen raw in small cooking portions; they soften after thawing but retain their heat for sauces and stews.

Method

  1. Choose firm, sound chillies. Wear gloves for hot varieties; wash, remove stalks and dry the pods completely.
  2. Leave small chillies whole or cut larger pods into rings or pieces. Remove seeds only if you want less heat in the portion.
  3. Spread pieces on a tray in one layer and freeze until firm if you want them to stay separate. No blanching is needed.
  4. Transfer to labelled airtight freezer bags or containers, press out excess air and return promptly to the freezer.
  5. Use the chillies from frozen in cooked dishes, or thaw the needed portion in the refrigerator. They become soft after thawing; do not refreeze thawed chillies.

Storage

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

Sliced red and green chillies pickled in a glass jar

Pickling Chilli

General preservation or storage guidance

Preparation About 1 hour active, plus jar processing and cooling

This tested hot-pepper pickle combines hot and sweet peppers in a fixed 5% vinegar brine and boiling-water process; do not change the ratio or process.

Method

  1. Wear rubber gloves when handling hot chillies. For about nine US pints, measure 1.8 kg (4 lb) hot long red, green or yellow peppers, 1.36 kg (3 lb) sweet red and green peppers, 1.2 litres (5 cups) white vinegar labelled 5% acidity, 240 ml (1 cup) water, 4 tsp pickling salt, 2 tbsp sugar and 2 garlic cloves.
  2. Wash peppers. Leave small chillies whole and slash each 2–4 times; quarter larger peppers. Blister skins under a hot grill or in a 200°C oven until blistered, cool enough to handle and peel.
  3. Flatten small peeled peppers and fill clean hot half-pint or pint jars, leaving 1.3 cm (½ in) headspace.
  4. Bring the measured vinegar, water, salt and sugar to the boil and simmer 10 minutes; remove the garlic. Cover the peppers with the hot liquid to the same headspace.
  5. Process 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 NCHFP canner instructions; do not shorten the time or alter vinegar strength, pepper ratio or jar size.
  6. Cool undisturbed and check seals. Refrigerate any unsealed jar and all 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 full tested process; no additional period stated

Chilli Flakes

General preservation or storage guidance

Preparation Preparation plus several hours in a dehydrator

Fully dried chilli pods can be crumbled into flakes for adding heat to cooked dishes.

Method

  1. Choose sound chillies, wash them and dry the surface completely; wear gloves when handling hot varieties.

  3. Dry with moving air until pods and seeds are brittle throughout, with no soft or damp sections.
  4. Cool completely, then crumble or pulse briefly into flakes, avoiding inhalation of chilli dust.
  5. Pack immediately in a clean airtight jar away from heat and moisture; discard if condensation or mould appears.

Storage

Airtight jar in a cool, dry, dark place · No exact period stated; inspect for moisture
