How do you make chutney that keeps for years and actually tastes good?

Chutney is the most forgiving of all preserving methods. Unlike jam, there is no critical set point to hit. Unlike fermentation, there is no risk of spoilage if you follow basic hygiene. You are essentially cooking down a mixture of fruit or vegetables with vinegar, sugar, and spices until thick, then sealing it in jars — and the result keeps for two to three years sealed, improving in flavour as it matures.

It is also the best method for using imperfect, overripe, or mixed harvests. A slightly bruised apple, an overgrown courgette, or tomatoes that cracked in the rain are all ideal chutney material. What matters is flavour, not cosmetic perfection.

The basic chutney ratio

A reliable starting point is: 1kg prepared fruit or vegetables, 500ml vinegar, 250–300g sugar, and aromatics (onion, garlic, ginger, dried spices) to taste. The vinegar and sugar quantities can vary — more vinegar makes it sharper, more sugar makes it sweeter and helps it thicken faster. Brown sugar and malt vinegar make a darker, more robust chutney; cider vinegar and white sugar make something lighter and more delicate. Both keep equally well.

Always use vinegar with at least 5% acetic acid — standard malt, cider, white wine, or red wine vinegars all qualify. Never dilute the vinegar or reduce it before adding — the full acid content is what preserves the chutney safely long-term.

How to make chutney step by step

Dice all fruit and vegetables into small, even pieces — roughly 1cm cubes. Finely chop onions and any garlic or ginger. Add everything to a large, heavy-based pan with the vinegar, sugar, and whole spices (tied in a muslin cloth if you want to remove them later). Bring to a gentle boil, stirring to dissolve the sugar, then reduce to a steady simmer. Do not rush this stage with a high heat — chutney catches and scorches easily on the bottom of the pan. Stir every few minutes and keep the heat moderate.

Cook uncovered for one to two hours, or until the chutney has reduced to a thick consistency with no pools of liquid on the surface. Draw a wooden spoon across the bottom of the pan — if the channel it leaves takes more than three seconds to fill with liquid, the chutney is ready. If it fills instantly, cook for another fifteen minutes and test again.

Jars and potting

Use only jars with vinegar-proof lids — metal lids with a plastic coating or lids lined with wax. Bare metal corrodes in contact with vinegar and ruins both the chutney and the seal. Sterilise jars in the oven at 140°C for fifteen minutes, exactly as you would for jam. Fill the hot chutney into hot jars to the brim — chutney shrinks as it cools, so a full jar is correct. Seal immediately and label with the date and ingredients.

When to eat chutney and how long it keeps

The hardest part of making chutney is leaving it alone. Fresh chutney is often sharp and the flavours are not yet integrated. Leave it sealed for at least six to eight weeks and the vinegar mellows, the spices deepen, and the whole thing becomes richer and more complex. Sealed jars keep for two to three years in a cool cupboard. Once opened, use within two months and keep in the fridge. If the colour dulls or you see any mould, discard — but this is rare if jars were properly sterilised and sealed.

What can you make chutney from?

Almost any garden vegetable or fruit works. Tomato chutney is a classic destination for a tomato glut. Green tomatoes make excellent chutney when the season ends and unripe fruit is left on the vine. Courgettes, runner beans, apples, pears, plums, beetroot, onions, and even pumpkin all make excellent chutneys, alone or mixed together.
