A beginner's guide to everyday ferments

Everyone starts somewhere, and fermented food can feel oddly intimidating for something so ancient and ordinary. The jars look mysterious, the flavours are bold, and the internet is full of people talking about it as though it's a lifestyle rather than lunch. Let's clear that away. You don't need special equipment, a stocked cellar, or any commitment beyond a normal grocery run. Fermented foods are already sitting on the shelves of most supermarkets, and getting started is simply a matter of buying a few, tasting them, and noticing what you like. The tang that puts some people off at first is exactly the thing regular eaters come to crave — sour, savoury, alive — and it grows on you faster than you'd expect. The goal of this guide is not to turn you into an expert. It's to get five useful, delicious jars into your fridge and give you the confidence to actually use them. Think of it as a starter kit: a small, forgiving collection that covers breakfast, lunch, and dinner, and teaches your palate what fermented food can do. Keep everything low-stakes and curious. There's no wrong way to enjoy a spoonful of yogurt.

One principle before the shopping list: always buy the plain, unsweetened version first. Plain yogurt, plain kefir, unsweetened kraut. Flavoured versions are often loaded with sugar and far less useful in cooking. You can always add honey or fruit yourself; you can't take the sugar back out.

The first five jars

1. Plain yogurt

The friendliest starting point, because almost everyone already likes it. Thick, creamy, gently tangy, it slots into sweet breakfasts and savoury dinners alike. Buy a plain, unsweetened tub — Greek-style if you want it extra thick — and use it as a topping, a dip base, or a cooling spoonful on anything spicy.

2. Kefir

Yogurt's livelier cousin: thinner, sharper, faintly fizzy. It pours rather than spoons, which makes it perfect for drinking straight, blending into smoothies, or using in place of buttermilk in a batter. Expect a bigger tang than yogurt — that's the point. Start with a small glass and see how you take to it.

3. Sauerkraut

Finely shredded fermented cabbage, clean and sour, with no chilli. It's the gentlest entry into fermented vegetables and a natural partner to rich, fatty food. Look for it in the chilled section (the shelf-stable kind is often just vinegar-pickled and doesn't taste the same). A forkful next to sausages, sandwiches, or roast potatoes shows immediately what it's for.

4. Kimchi

The bolder cousin of kraut — fermented vegetables, usually cabbage, with garlic, ginger, and chilli. It's sour, savoury, and a little spicy, and it's one of the most versatile jars you can own: eat it cold as a side, or cook with it once it's tangy. If the spice worries you, start with a small amount alongside plain rice.

5. Miso

A tub of fermented soybean paste that keeps for months and adds deep, savoury richness to anything. Start with a lighter (white) miso, which is milder and sweeter. Whisk a little into a dressing, stir a spoon into a soup or pan sauce near the end, and you'll see why cooks treat it like a secret weapon.

Buy plain, taste slowly, and start small. Five jars in the fridge will teach you more about fermented food than any amount of reading.

Building a taste for the tang

If sourness isn't yet your thing, ease in. Pair a small amount of a ferment with something plain and familiar — kraut with a sandwich, kimchi with rice, yogurt with fruit — so the tang has a soft landing. Taste a little at a time rather than committing to a big serving. And give it a few tries; palates adjust quickly, and the flavour that reads as "too much" in week one often becomes the thing you reach for by week three. There's no rush and no test at the end.

Storing your starter kit

Keep everything in the fridge, keep lids clean, and use a clean spoon each time so you don't introduce anything unwanted. Most of these jars last weeks, and several — kimchi and kraut especially — actually improve with a little age, growing tangier and more complex. That means your starter kit gets better while it sits there, which is a rare and lovely thing for a fridge to do.

That's genuinely all there is to starting. No crocks, no waiting, no expertise. Just a handful of jars, a curious spoon, and a week or two of tasting. Once these five feel like old friends, the rest of the fermented world — the injera, the kvass, the countless regional pickles — is yours to explore whenever you like.
