Rainbow Chard Kimchi
Inspired by the popular Korean lacto-fermented side dish, this recipe for kimchi uses rainbow chard instead of cabbage.
From the book
Kimchi is a spicy fermented dish from Korea traditionally made with cabbage. Here, chard supplies the same textural mix of soft leaves and crunchy ribs and stalks, while the fermenting process foregrounds the earthy, almost smoky beetroot flavours of this root vegetable relative. Try experimenting with other leafy greens, such as kale, pak choi, and collards.
|large bunch (around 500g/1lb) of||rainbow chard, leaves roughly shredded and stalks chopped into large chunks|
|bunch of||dill, finely chopped|
|2||fat garlic cloves, sliced|
|5cm (2in)||knob of ginger, peeled and finely chopped|
|1 or 2||red bird’s eye chillies, finely chopped|
|fine sea salt|
You will need: 1-litre (1¾ pint) preserving or fermentation jar, sterilised, pestle or rolling pin (optional).
Prepare enough chard to fill the preserving jar almost to the top, tightly packed in. Test the fit and weigh the chard. Prepare the dill, garlic, ginger, and chilli but keep separate; weigh these as well, then set aside. Measure out 2–3 per cent of the total weight in salt.
Place the chard in a large bowl and sprinkle over the salt. Massage the salt into the chard, until it begins to release beads of water and starts to soften. Leave for a couple of hours to let osmosis take effect.
Place the salted chard and any juices into the jar, scattering over the herbs and spices with each handful. Pack in the vegetables tightly, pressing them down as you go and eliminating air pockets between layers. Use a pestle or the end of a rolling pin to tamp down the ingredients.
Top up the jar with water, if needed, so that the vegetables are submerged. Cut a disc of baking parchment large enough to cover the contents of the jar, with some excess. Place the disc over the vegetables, pressing it down and into the edges to ensure the surface is completely covered.
Seal the jar and date and label the contents. Leave to ferment at room temperature, out of direct sunlight, for 1–2 weeks. Taste regularly after 1 week, until the preferred degree of sourness is reached, then transfer to the fridge, where it will keep for several months.
Expert tips: Spread the salt over the greatest surface area to increase osmosis: massage thoroughly and get it right into any crevices.
The parchment keeps ingredients submerged to maintain an anaerobic environment. A plastic bag fi lled with air is an effective alternative, or you can buy jars with built-in airlocks.
Look out for small bubbles of carbon dioxide, a sign that fermentation is in full swing. If the process is slow to get going, try moving the jar to a warmer spot.
