Appelcompote
Appelcompote is the apple left with its dignity: soft enough to spoon beside pork or potatoes, still chunky enough to remind you autumn did the real work.

In my grandmother's second notebook, the preserves were not only fruit. That surprises people. They expect cherries, plums, redcurrants, all respectable citizens of the jam shelf, and then there is onion, the kitchen's most ordinary bulb, slowly persuaded into something glossy and dark enough to sit beside old cheese without embarrassment.
The name already tells you the trick, but politely. Ui is onion, plain as a clog by the door; confituur is the preserve, borrowed through French cookery from confire, to preserve. The Dutch use jam more often now, but confituur keeps the older promise: sugar, acid, patience, and a jar that buys time. But let me tell you a secret. Uienconfituur is not fancy food pretending to be rustic. It is frugal food behaving beautifully.
The spice cupboard matters here. A pinch of speculaaskruiden, that mixture of cinnamon, clove, nutmeg, mace, ginger, and white pepper, turns the onions toward the old Dutch table, where sweet and spiced were never strangers to meat, cheese, or brown bread. Cook the onions low enough that they collapse without scorching, then sharpen them with vinegar so the sweetness doesn't become dull. Hou het altijd simpel, always keep it simple: a pan, a spoon, and enough time for the onion to stop being sharp and start being generous.
Uienconfituur belongs to the Low Countries' long preserving habit, where sugar and vinegar were used not only for fruit but also for onions, cucumbers, cabbage, and other larder vegetables. The word confituur entered Dutch through French confiture, while the spicing reflects the everyday Dutch use of imported cinnamon, clove, mace, and nutmeg that became familiar through seventeenth-century trade. In modern Dutch kitchens it is most often served with aged Gouda, goat cheese, pate, cold roast meats, or bitterballen, a make-ahead condiment with older preserving logic behind it.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Heavy-bottomed saucepan or small Dutch oven
- •Wooden spoon
- •Two clean 250ml jars with lids
Instructions
- 1
Soften the onions
Warm the oil or butter in a heavy pan over medium-low heat. Add the sliced onions and salt, then cook for 20 to 25 minutes, stirring now and then, until the onions slump, turn translucent, and give up their sharp raw smell. Do not brown them hard. You want sweetness slowly drawn out, not bitterness dragged in.

Add sugar and spice
Stir in the dark brown sugar, bay leaf, speculaaskruiden, black pepper, and mustard seeds if using. Cook for 5 minutes until the sugar melts into the onions and the pan looks glossy. This is where the preserve turns Dutch: the spice should sit in the background like a warm room, not march across the table.
- 3
Simmer to jam
Add the cider vinegar, red wine vinegar, and water. Bring to a quiet simmer, then cook uncovered for 35 to 45 minutes, stirring more often toward the end, until the onions are dark, sticky, and spoonable. Draw the spoon through the pan; if the liquid closes slowly behind it, you are there. If it runs like soup, give it ten minutes more.

Jar and rest
Remove the bay leaf and spoon the hot confituur into two clean warm jars. Let it cool, then refrigerate. It is good the same day, but better after 24 hours, when the vinegar settles and the spices stop shouting at one another.
Chef Tips
- •Use ordinary firm storage onions. This is winter-larder cooking, and expensive sweet onions can make the preserve too soft and sugary.
- •Speculaaskruiden varies by maker. If yours is heavy with clove, use a light teaspoon; clove is a guest here, not the landlord.
- •Serve with aged Gouda, goat cheese, liver pate, cold roast pork, bitterballen, or a thick slice of brown bread with butter. The vinegar is there to cut richness, so don't make the confituur timid.
- •This is refrigerator preserving, not shelf-stable canning. Keep it chilled and use a clean spoon each time.
Advance Preparation
- •Best made at least one day ahead; the flavor rounds out after a night in the refrigerator.
- •Keeps for 2 weeks refrigerated in clean jars. For longer storage, use a tested water-bath canning method with verified acidity.
