If you have a surplus of courgettes from the garden, fermenting them is a simple and delicious way to preserve the harvest. Fermentation not only extends the shelf life but also adds beneficial probiotics and a tangy, complex flavour.
Why Ferment Courgettes?
Fermenting vegetables is an age-old preservation method that requires minimal equipment. The process uses salt and time to encourage beneficial bacteria, which produce lactic acid, naturally preserving the vegetables. According to fermentation expert Sandor Katz, "Fermentation makes vegetables more digestible and enhances their nutritional value." For courgettes, this method transforms their texture into a crisp, pickle-like consistency.
Ingredients and Equipment
To ferment courgettes, you need: 1 kg of fresh courgettes, 2 tablespoons of sea salt (non-iodized), 1 liter of filtered water, and optional flavourings such as garlic, dill, or chilli flakes. Equipment includes a clean glass jar (1-2 litre capacity), a weight to keep vegetables submerged, and a lid with an airlock or a regular lid that you can burp daily.
Step-by-Step Instructions
Wash the courgettes and slice them into rounds or spears. Dissolve the salt in water to create a brine. Pack the courgettes tightly into the jar along with any aromatics. Pour the brine over the vegetables, ensuring they are fully submerged. Place a weight on top to keep them under the brine. Seal the jar with an airlock lid or tighten the regular lid, then loosen slightly to allow gas to escape. Store at room temperature (18-22°C) for 5-10 days, checking daily for mold and tasting after 5 days. Once fermented to your liking, transfer to the refrigerator.
Tips for Success
Use fresh, blemish-free courgettes. Avoid using iodized salt as it can inhibit fermentation. Keep vegetables submerged to prevent mold. If mold appears on the surface, skim it off; the vegetables below are usually fine. The brine may become cloudy, which is a sign of healthy fermentation. Fermented courgettes will keep for several months in the fridge.
How to Use Fermented Courgettes
Enjoy them as a tangy snack, chopped into salads, or as a side to grilled meats and cheeses. They add a probiotic boost to any meal. Start with a small batch to perfect your technique, then scale up as you like.
