PRESERVING GUIDE

Preserving Courgettes

Use a glut quickly in chutney, relish or frozen grated portions.

Courgette chutney

Courgette Chutney

General preservation or storage guidance

Preparation About 1 hour active

A cooked courgette and apple chutney makes soft, spiced pieces for serving from the fridge or freezer; this version is not a pantry preserve.

Method

  1. Use 750 g young courgettes, 2 peeled and cored cooking apples, 1 medium onion, 150 ml cider vinegar, 100 g brown sugar, 1 tsp mustard seed, ½ tsp ground ginger and a pinch of salt. Wash the vegetables; trim courgette ends and dice courgettes, apples and onion to similar small pieces.
  2. Put the courgette, apple, onion, vinegar, sugar, mustard seed, ginger and salt in a wide non-reactive pan. Stir over low heat until the sugar dissolves.
  3. Bring to a gentle simmer, then cook uncovered for 35–45 minutes, stirring regularly and more often as the liquid reduces. Keep the heat low enough to prevent scorching.
  4. The chutney is ready for this fresh-cooked version when the courgette is tender and a spoon drawn across the pan leaves a trail that closes slowly; do not use this visual cue to claim shelf stability.
  5. Spoon into shallow clean containers, cool promptly and refrigerate within 2 hours. Keep at or below 5°C and use within 48 hours, or freeze promptly in labelled portions. This is not a room-temperature preserve.

Storage

Refrigerator at or below 5°C, or freeze in portions · Refrigerated cooked food: use within 48 hours, or freeze promptly

Courgette slices prepared for freezing

Freezing Courgettes

General preservation or storage guidance

Preparation About 30 min active, plus cooling

Young courgettes freeze best as blanched slices or briefly steamed grated portions for later cooking and baking.

Method

  1. Choose young courgettes with tender skins; wash and trim the ends.
  2. For slices, cut into 12 mm rounds. Blanch in boiling water for 3 minutes, then cool promptly in cold water and drain.
  3. For grated courgette intended for baking, grate it and steam-blanch small batches for 1–2 minutes until translucent; cool the measured portions in cold water.
  4. Drain thoroughly and pack slices or measured grated portions into freezer-safe containers, leaving expansion space. Freeze slices on a tray first if you want them separate.
  5. Seal, label and freeze promptly. Thawed courgette softens, so use it in cooked dishes or baking rather than expecting a crisp texture.

Courgette slices drying on mesh trays

Drying Courgettes

General preservation or storage guidance

Preparation 20 min active; about 8–10 hours in a dehydrator

Thin courgette slices dry into crisp vegetable chips or pieces for soups; the low-moisture finish matters for storage.

Method

  1. Choose small, firm courgettes, wash them and trim the ends.
  2. Cut into uniform 5–6 mm slices; thinner pieces dry faster but are fragile.
  3. Spread slices in one layer on dehydrator trays without overlap, allowing air to circulate.
  4. Dry at about 60–63°C for roughly 8–10 hours, checking at the end; slices should be crisp and brittle throughout, not leathery or damp in the centre.
  5. Cool completely before packing airtight. Store cool, dry and dark; check for condensation and discard any mouldy pieces.

Storage

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

Pickled courgette slices in a clear jar

Pickling Courgettes

General preservation or storage guidance

Preparation About 45 minutes active, plus 1 hour chilling

Tender courgette slices take on a sweet mustard-and-turmeric brine; this specific summer-squash pickle must stay refrigerated.

Method

  1. For one batch, measure 4 cups tender courgette slices, 1 cup chopped onion, 1 chopped red pepper, 1 chopped green pepper, ¼ cup pickling salt, 1½ cups sugar, 1 cup white vinegar, 1 tsp mustard seed, 1 tsp celery seed and 1 tsp turmeric.
  2. Wash the courgettes and peppers. Trim courgette ends and slice thinly; remove pepper stems, seeds and white membranes, then chop with the peeled onion.
  3. Mix the vegetables with the salt and 1 cup cold water. Cover and chill in the refrigerator for 1 hour. Drain well and rinse twice with cold water.
  4. Bring the measured vinegar and sugar to a boil with the mustard and celery seeds. Stir until dissolved, then pour the hot liquid over the drained vegetables.
  5. Transfer to a clean refrigerator-safe container with a lid. Cool, cover and refrigerate promptly; keep at or below 5°C. This recipe is not processed for pantry storage.
  6. Use the pickled courgettes within 7 days; discard them sooner if mould, an off smell or an unusual texture develops.

Storage

Refrigerator at or below 5°C; not suitable for cupboard storage · Use within 7 days
