Quick homemade piccalilli: a proper recipe that actually works

The salting step takes a few hours, but your hands-on time is under an hour, and the end result is sharply spiced, properly mustardy, and genuinely nothing like the watery stuff you get in most supermarket jars.

It costs very little to make, and works with almost any firm vegetables you have knocking about.

What piccalilli actually is

It's a British pickled vegetable condiment with Indian spice influences, which is why it tastes quite different to, say, a plain vinegar pickle.

The yellow colour comes from turmeric, and the thick, slightly sticky sauce is down to a flour and mustard base. It's been a staple in British kitchens since at least the mid-18th century, the Oxford English Dictionary traces the name to 1758, when Hannah Glasse described how to make "Paco-Lilla, or India Pickle", and it's traditionally made in late summer when courgettes and cauliflower are cheap and plentiful.

The flavour sits somewhere between pickle and chutney: sharp from the vinegar, warm from the mustard and turmeric, with as much heat as you want. It's what makes a ploughman's lunch actually interesting.

The vegetables

You need about 1kg of prepared vegetables in total. Cauliflower is the backbone of any piccalilli, so use at least half of that as florets. Beyond that, traditional additions include courgette, green beans, shallots, and cucumber. Some people add baby corn or peppers.

The main rule is that everything needs to be firm enough to hold its shape after pickling, which rules out tomatoes or anything too watery.

Cut everything into small, even pieces, roughly 1 to 2cm. Go too big and they won't absorb the pickling liquor properly; go too small and they'll go mushy.

Salting: don't skip this

Put all your cut vegetables in a large bowl, scatter over 50g of fine salt, toss everything together, cover, and leave it for at least four hours. Overnight is better. This draws out excess moisture so your final piccalilli isn't watery and your sauce thickens up properly.

After the salting time, drain the vegetables and rinse them thoroughly under cold water. Then spread them out on a clean tea towel and pat them dry. If they go into the pan wet, the sauce won't thicken the way it should.

The spice mix

This is what makes piccalilli taste like piccalilli rather than just vinegared veg. For 1kg of vegetables you'll need:

2 tsp ground turmeric

2 tsp English mustard powder

1 tsp ground ginger

1 tsp yellow mustard seeds

1/2 tsp ground cumin

1/4 tsp chilli flakes (optional, but recommended)

30g plain flour

400ml white wine vinegar or cider vinegar

60g caster sugar

A note on vinegar: malt vinegar will give you a darker, sharper result. White wine or cider vinegar keeps the yellow colour and gives a slightly milder flavour.

Neither is wrong, it's just a different pickle.

How to make the sauce

Warm a splash of the vinegar in a large heavy-bottomed pan, then add the turmeric, mustard powder, ginger, mustard seeds, and cumin. Stir over a low heat for about a minute so the spices cook out slightly. This makes a real difference to the flavour.

Mix the flour with a small amount of the remaining cold vinegar to make a smooth paste, then add that to the pan along with the rest of the vinegar and the sugar. Stir continuously over a medium heat until the sauce thickens. It should coat the back of a spoon, which usually takes around five to eight minutes.

Add the drained, dried vegetables to the sauce and stir to coat everything evenly. Cook for another three to four minutes. You want the vegetables to warm through and absorb some of the sauce, but not go limp, they should still have a bit of bite.

Potting up

Spoon the piccalilli into sterilised jars while it's still hot. To sterilise jars, wash them in hot soapy water, rinse, then put them in an oven at 140°C for about fifteen minutes. Add the lids for the last five minutes.

Fill the jars right to the top to reduce the air gap, then seal immediately. You should hear the lids pop as they cool, which means you've got a good seal.

This recipe makes around two to three 400g jars, depending on how tightly you pack them.

How long before you can eat it

Here's the part most people get wrong: piccalilli needs time to mature. If you open a jar the next day, it'll taste harsh and the spices won't have come together properly.

Leave it for at least two weeks, and ideally four. The flavour mellows and deepens considerably in that time.

Unopened jars keep for up to a year in a cool, dark cupboard. Once opened, keep in the fridge and use within six weeks.

A few things worth knowing

Don't be alarmed by how strongly it smells while it's cooking. The vinegar and turmeric together are fairly pungent, but it calms right down once it's jarred and rested.

The sauce will also thicken further as it cools and then again as it sits in the jar. If it looks a bit loose when you're potting up, that's fine.

It's one of the most practical things you can make: low cost, long shelf life, and it lifts a very ordinary cheese sandwich into something worth eating.
