Beetroot Chutney

This is a quick, small batch of beetroot chutney with apple, onion and fresh ginger, cooked in under an hour once the beetroot is tender. It differs from most chutneys in one way: it goes into the fridge as soon as it has cooled, never the cupboard, and it has to be eaten within 10 days of making.

Why this chutney lives in the fridge

Beetroot is a low-acid vegetable. A chutney keeps safely at room temperature only when it is acidic enough (pH 4.5 or lower) evenly all the way through, or dry enough, for its whole shelf life. That can't be judged by eye or taste. A research-tested recipe, one worked out by food scientists who have checked its acidity, is how you know a jar reaches it, as long as you follow it exactly.

Thickened beetroot mixtures, chutney included, have no research-tested recipe for keeping at room temperature, and this recipe has a modest amount of vinegar for the weight of vegetables and fruit. So you can't be sure it is acidic enough for the cupboard. Scottish council environmental health guidance says chutneys like that go in the fridge even before they're opened, and Orkney Islands Council sets their maximum shelf life at 10 days.

The year's keeping usually given for chutney is for chutneys made to a tested recipe, with plenty of vinegar, sealed hot and stored in a cool, dark cupboard.

If you want beetroot in jars for the winter cupboard, make pickled beetroot instead. It is a tested recipe with enough vinegar and a spell in a pan of boiling water after the jars are filled, and it keeps only if you do both. For a chutney that keeps for months, apple chutney is a tested cupboard recipe. The full picture for every kind of preserve is in how long preserves keep.

Keep the recipe as written

• Use malt vinegar labelled at least 5% acidity.
• Don't reduce the vinegar, and don't change the proportions of vinegar, vegetables and fruit.
• Keep the sugar as written.
• Cook it in stainless steel or unchipped enamel. Copper, brass, iron and galvanised metal can react with the vinegar and salt.

The fridge does most of the safety work here, but the vinegar and sugar still matter: the vinegar's acidity holds back bacteria, moulds and yeasts, so don't treat the fridge as licence to cut either. Nor does adding extra vinegar turn it into a cupboard chutney. Swapping more apple for beetroot, or adding other vegetables, changes the balance too; mixing fruit and veg in preserves explains why.

Keep the batch small: all of it has to be eaten in 10 days, and a bigger pan takes longer to cool. Don't make more than you'll eat in that time, and if you do scale up, change every ingredient by exactly the same amount.

Beetroot from the plot

Beetroot much bigger than about 7.5 cm across is often fibrous, so smaller roots suit this recipe best. The beetroot growing guide covers sowing and lifting.

Freshly lifted beetroot keeps about two weeks in the fridge if you leave it unwashed, with about 5 cm of stem on, in a plastic bag. Trim it back to 2.5 cm when you come to cook it. That gives you time to make a batch of chutney when it suits you rather than the day you dig. For a bigger crop, storing beetroot for winter covers keeping roots for months, so you can make a fresh fridge batch whenever you want one.

Jars and lids

Use clean, sterilised jars without chips or cracks, and new lids. Sterilising is good hygiene rather than a way to stretch the keeping time. The guide to jars for preserving helps with choosing jars and lids that stand up to vinegar.

When to throw it out

Some moulds and yeasts can grow even in sugary, acidic food. Throw the chutney out without tasting it if you see any mould, if it smells fermented, yeasty or otherwise wrong, if it bubbles or liquid spurts out when you open the jar, or if it reaches 10 days from the date on the lid.
