Beyond the flavour, fermented vegetables are something of a nutritional powerhouse. They’re rich in live probiotic bacteria that support a healthy, diverse gut microbiome, and a happy gut has ripple effects throughout the body. Regular consumption has been linked to improved digestion, reduced bloating, and a strengthened immune system.
This is the ideal first ferment: forgiving, endlessly adaptable, and ready in a matter of days.
Ingredients
- 25g sea salt, pickling salt or kosher salt
- 475ml water
- 75g small cauliflower florets
- 75g carrot chunks or slices
- 75g red onion, sliced
- 1 clove garlic, peeled and smashed
- 1 bay leaf
- ¼ tsp coriander seeds
- ⅛ tsp black peppercorns
Instructions
- Combine the salt and water in a measuring jug and stir until dissolved. You can heat the water first to help the salt dissolve, but let it return to room temperature before continuing.
- Place the chopped vegetables, garlic, bay leaf, coriander seeds and peppercorns in a very clean 1-litre jar. Pour the brine over the vegetables, leaving at least 2.5cm of headspace at the top. Top up with water if needed to cover everything. A small pickling weight will help hold the veg below the brine.
- Cover the jar tightly and leave at room temperature. About once a day, open the jar to taste the pickles and release the gases produced during fermentation.
- When the pickles taste just right to you, transfer the jar to the fridge. Cold storage largely halts fermentation, though they’ll continue to develop very slowly.
Make it your own: Almost any vegetable combination works, so use this recipe as a template. Just be sure to use whole spices rather than ground ones, which will cloud your brine. Mustard seeds, dill seeds, juniper berries, red chilli flakes, or fresh additions like dill sprigs, horseradish, ginger or thyme all bring wonderful variety.
Take your skills further
Fermenting is one of those skills that rewards curiosity. Once you’ve made your first jar, you’ll want to try everything. If you’d like to learn hands-on, there’s no better place to start than in the garden itself.
We’ve teamed up with the Royal Botanic Garden Edinburgh for our Fermenting & Pickling: Gardener & Chef Series, part of the Botanics’ Gardener & Chef programme. You’ll be guided through the Botanics’ own Kitchen Garden by a garden expert to discover what’s in season and how to grow and live more sustainably, followed by a 90-minute fermenting and pickling demonstration led by one of our skilled cookery teachers, with tasty treats to enjoy along the way. It’s a relaxed, 3.5-hour day that takes you from soil to jar.
Classes run on 11th July, 8th August and 5th September 2026 (£126, with a discounted rate for RBGE members). Find out more and book your place here.
