Roasted Sweet Beet Relish

This roasted sweet beetroot relish is a vibrant, deeply flavoured condiment that balances earthy sweetness with the sharp heat of fresh horseradish. By slowly roasting the tomatoes and beetroots first, the sugars caramelise to create a rich, concentrated base that far surpasses any shop-bought alternative. The addition of balsamic and red wine vinegar provides a bright acidity, making this a quintessential preserve for the larder.

As a versatile vegan relish, it pairs beautifully with plant-based burgers, mature cheeses, or as a colourful accompaniment to a Sunday roast. This recipe is an excellent way to use a seasonal harvest of young beetroots, and the jars also make thoughtful homemade gifts. For the best flavour, allow the relish to mature for a few days before opening.

Ingredients for Roasted Sweet Beet Relish

  • 1.0kg tomatoes

  • 2 teaspoons sea salt

  • 4 garlic cloves, peeled and sliced

  • 60ml olive oil

  • 1.0kg young, small beets, trimmed

  • Olive oil, for drizzling

  • 300ml granulated sugar

  • 160ml red wine vinegar

  • 2 tablespoons balsamic vinegar

  • 1 large red onion, peeled and finely chopped

  • 60g freshly grated horseradish root (or pickled horseradish, see below)

How to make Roasted Sweet Beet Relish

Preheat the oven to 177°C. For the tomato purée, halve the tomatoes and place them, skin side down, on a baking sheet. Sprinkle with the salt, garlic, and olive oil. Roast for 1 hour on the bottom shelf of the oven, then remove. Press through a sieve or pass through a food mill to remove the skins and seeds – you’ll end up with about 300ml intensely flavoured purée.

Meanwhile, put the beets into a baking dish and drizzle with a little olive oil. Roast, above the tomatoes, for 1 to 1 1/2 hours (longer if necessary), until the skins are blistered, blackened, and loosened. Let cool a little before peeling. You’ll find the skins will slide off easily. Coarsely grate the beets (a food processor makes this job easy).

Put the sugar, vinegars, onion, and horseradish into a large saucepan; bring to a boil and cook for 5 minutes. Stir in the tomato purée and cook for a couple minutes more. Finally, add the grated beets and cook for about 10 minutes, until thickened. Transfer to sterilized jars and seal with vinegar-proof lids (see pp. 21–22). Use within 1 year. Refrigerate once opened.

It’s easy to pickle horseradish root. Just grate enough fresh root to fill a jam jar, sprinkle with 1 teaspoon of salt and 1 teaspoon of sugar, top up with cider vinegar, and seal with a lid. Use in sauces, dressings, and soups, and serve with roast beef.
