Brussels Sprout Kimchi

This Brussels sprout kimchi offers a vibrant, modern twist on traditional Korean fermentation. By replacing the usual cabbage with halved sprouts, you create a crunchy, punchy condiment that balances the earthy notes of the vegetable with the heat of gochugaru and Sriracha. The addition of crushed coriander and fennel seeds provides a subtle aromatic depth, making this savoury preserve a versatile addition to your fridge.

As a dairy-free ferment, this dish is naturally rich in probiotics and serves as a healthy way to preserve seasonal produce. It is the perfect accompaniment to grilled meats, steamed rice, or even stirred through a quick mid-week stir-fry. While delicious after just a few days of fermenting, the flavours will continue to deepen and develop over several weeks in the fridge.

How to make Brussels Sprout Kimchi

Combine 100g salt and 1.9L warm water in a large bowl, whisking to dissolve salt. Add brussels sprouts and top with a plate to keep brussels sprouts submerged. Let sit at room temperature 4 hours; drain. Rinse, drain, and place in a large bowl.

Pulse onion, spring onions, garlic, gochugaru, fish sauce, Sriracha, ginger, soy sauce, and coriander and fennel seeds in a food processor until smooth. Add to bowl with brussels sprouts and toss. Transfer to two 900g canning jars, packing down to eliminate air gaps.

Combine remaining .200g salt and 0.9L warm water in a large bowl, whisking to dissolve salt. Add pickling liquid to jars to cover brussels sprouts, leaving at least 1" headspace. Cover jars with lids. Let sit out of direct sunlight at room temperature until kimchi tastes tangy and releases bubbles when stirred, 3-5 days. Chill.

DO AHEAD: Kimchi can be made 2 months ahead (flavour will deepen). Keep chilled.
