When the Pepper Glut Arrives

Late summer in Tunisia is a hot, red affair. Market stalls in Nabeul and Bizerte disappear under crates of peppers, and households buy them by the sack rather than the handful. In a country where the growing season is generous but the winter months are lean on fresh vegetables, preserving is not nostalgia — it is ordinary kitchen economy, handed down through generations of cooks who knew exactly how much a full pantry matters in January.

That same instinct travels very well to a British kitchen. An allotment glut, a reduced-to-clear tray at the market, or a neighbour's greenhouse surplus can all be turned into jars that earn their place on the shelf. Peppers are the backbone of North African cooking: they give harissa its colour, couscous its sweetness, and a plain salad its point. When they are cheap and plentiful, they are also among the easiest things in the world to put by.

The Peppers Worth Keeping

Not every pepper preserves equally well. Thick-fleshed, sweet-hot varieties hold their shape and flavour best, while thin-skinned ones tend to soften faster but roast beautifully.

• Baklouti — the classic Tunisian pepper, sweet at first with a slow warmth behind it. Ideal for oil preservation and for harissa.
• Long pointed red peppers — widely sold in the UK, cheap in late summer, and excellent roasted and peeled.
• Bell peppers — the reliable substitute. Sweeter and milder, but they take vinegar beautifully and add bulk to a jar.
• Small chillies — preserved whole, ready to be chopped into anything that needs a lift.

Whichever you choose, look for firm, glossy, unblemished skins with no soft patches. A slight bend is fine; a bruise is not. Wash and dry them thoroughly before you begin, and discard anything already beginning to wrinkle or weep.

Preserved in Oil: The Slow, Generous Method

This is the method most closely associated with Tunisian home cooking, and it rewards patience. Grill or roast the peppers whole until the skins blister and blacken, then cover them in a bowl and let them steam for ten minutes — the skins will slip away easily. Peel, remove the stalks, seeds and pale membranes, and lay the flesh in a colander.

Now salt them properly. A generous scattering of coarse sea salt, then leave them to drain overnight, ideally weighted, so the excess water runs away. Some cooks go further and dry the salted peppers in the sun for a day or two; in a British autumn, a warm airing cupboard or a low oven left ajar will do a similar job. Moisture is the enemy here, so do not rush this stage.

Pack the drained peppers into sterilised jars in layers, adding sliced garlic, thyme, bay leaves, a few fennel or coriander seeds, and a dried chilli if you like. Cover completely with good olive oil, pressing down to release trapped air pockets. Keep a clear layer of oil above the peppers at all times. Store in the fridge and use within three or four months.

Vinegar and Brine: Sharper, Faster, Just as Useful

If oil preservation feels like a project, pickling is a pleasure you can finish in an afternoon. Bring equal parts white wine vinegar and water to the boil with salt, a little sugar, peppercorns, garlic and bay. Pack roasted or raw sliced peppers into jars and pour the hot liquid over, leaving a centimetre of headspace. Seal, cool, and leave for a fortnight before opening. The result is bright and bracing — exactly what a rich winter stew needs alongside it.

For whole chillies, a simple brine works beautifully: roughly 50g of salt to a litre of water, poured over pricked chillies with a couple of garlic cloves. Leave them at room temperature for a few days to ferment lightly, then move to the fridge. The brine turns slightly cloudy, the chillies soften, and the flavour deepens into something far more interesting than vinegar alone can manage.

From Jar to Table

These jars are not decoration. They are working ingredients, and they get used constantly.

• Chopped roughly with tuna, boiled egg, olives and capers for a robust winter version of salade méchouia.
• Layered into sandwiches with cheese, a smear of harissa and good bread.
• Stirred into stews, braises and tagines in the last few minutes, where they add brightness that long cooking destroys.
• Blitzed with garlic, caraway and chilli for a fast, fresh harissa.
• Served alongside grilled fish, roast chicken or folded through couscous.
• The oil left in the jar used as a dressing, warmed through with lemon.

A Few Rules That Keep the Pantry Safe

• Sterilise properly. Wash jars and lids, dry them in a low oven, and fill while still warm.
• Keep everything submerged. Peppers poking above the oil or brine will mould. Top up as you use the jar.
• Respect the salt and acid. They are doing the preserving. Reducing them for taste shortens the shelf life.
• Refrigerate oil-preserved peppers. Oil alone is not a safe preserving medium for anything containing moisture, so keep these jars cold and use them within a few months.
• Trust your senses. Fizzing, off-smells or fuzzy growth mean the jar goes in the bin, however good it looked last week.

Fill a shelf with these jars in September and you will cook from them all winter — a little sunshine, patiently kept, spooned into the grey months.
