Harvesting Capsicum
When ready: Green capsicums: full-sized, firm, glossy skin. Coloured capsicums: leave on plant 2-3 weeks past green stage until fully coloured (red, yellow, orange depending on variety). Coloured fruit is sweeter with higher vitamin C.
How to harvest: Cut with sharp secateurs leaving a short stem. Do not pull. This damages the plant. Harvest in morning when firm and cool.

- Freezing (Raw). Wash, deseed, cut into strips or dice. Spread on tray to flash-freeze. Bag. No blanching needed for capsicums. Texture will be soft when thawed. Best for cooking, not raw eating. Keeps: 12 months.
- Roasting and Freezing. Roast whole capsicums at 220C until skin blackens and blisters. Place in sealed bag to steam 10 minutes. Peel off skin, deseed, tear into strips. Freeze flat in bags with any collected juices. Keeps: 12 months.
- Dehydrating. Deseed and cut into strips or rings. Arrange on dehydrator trays. Dry at 60C for 8-12 hours until leathery or crispy. Store in airtight jars. Grind dried capsicum into paprika powder. Keeps: 12 months.
- Pickled (Roasted Capsicum in Vinegar). Roast and peel capsicums. Pack into sterilised jars with garlic and basil. Cover with white wine vinegar. Seal. Process in boiling water bath for 15 minutes. Keeps: 12 months.
