White Cheese, Big Personality: A Practical Sirene Handbook for UK Kitchens

There are cheeses you serve. Sirene is a cheese you keep. It lives in a tub in the fridge, gets crumbled over tomatoes at breakfast, folded into eggs on a grey Tuesday, and spooned onto the table whenever someone says they are not really hungry. For Bulgarian families in Britain, it is less a specialist ingredient than a household habit.

That is also why buying it here can feel oddly complicated. The UK has no shortage of white cheese. It has feta, Greek-style salad cheese, halloumi, ricotta, cottage cheese and a hundred yoghurt-adjacent things in tubs. What it does not always have is the specific salty, crumbly, slightly tangy character of sirene. So here is a practical guide for 2026: what to look for, where to look, and what to do once you get it home.

First, what are we actually looking for?

Sirene is a brined white cheese, usually made from sheep's milk, cow's milk, or a blend of the two. It is salted, stored in brine, and eaten young. Good sirene is white and slightly uneven, crumbles rather than slices, and has a clean dairy tang rather than a sharp vinegar hit. It can be creamy, but it should not be soupy. It can be salty, but it should not taste like a mistake.

In Bulgaria it appears at breakfast with tomatoes and bread, in shopska salad, inside banitsa, on top of baked peppers, and beside rakia when someone insists there is no proper meal without it. It is not a fancy cheese. It is a useful one.

The closest familiar UK comparison is feta, but they are not identical. Feta has protected status and a slightly firmer, creamier profile. Sirene can be softer, saltier and more crumbly, depending on the maker. Treat feta as a cousin, not a stand-in with the same passport.

The UK shop shelf: what passes muster

Supermarkets are better than they used to be. Most large branches now stock feta-style cheese in brine, often labelled 'Greek salad cheese' or simply 'white cheese'. These are fine for a weeknight salad, but read the label. If it is packed in oil rather than brine, it will taste more like a marinated cheese than sirene. If it is very rubbery, it may be closer to a grilling cheese. Own-brand versions vary wildly, so buy small first.

For something closer to the real thing, head to Eastern European delis. Polish, Romanian, Turkish and Bulgarian shops often carry brined white cheese in tubs or vacuum packs. Ask for sirene by name, or for Bulgarian white cheese. The staff may offer you a taste, and you should say yes. In cities with larger Bulgarian communities — London, Birmingham, Manchester, Edinburgh — these shops are also social hubs, noticeboards and sources of good advice about which brand is currently worth buying.

Online suppliers fill the gaps. Specialist Bulgarian and Eastern European grocers sell tubs and vacuum packs, sometimes in larger catering sizes. Check that chilled delivery is available, especially in warm months, and buy from shops that move stock quickly. Brined cheese keeps well, but it is not immortal. If you are ordering a large tub, split it with a friend or plan to cook with it.

How to read a tub without a translator

Look at the milk first. Sheep's milk sirene tends to be richer and tangier; cow's milk versions are milder and often cheaper. A blend can be excellent. Then look at the brine. Properly brined cheese should be white and fresh-looking, not yellowing at the edges. When you open it, the smell should be clean and dairy-like. If it smells sharply of ammonia or old fridge, take it back.

Once open, keep the cheese in its brine in a clean jar in the fridge. If it is too salty for your taste, rinse it briefly under cold water and pat it dry. Do not leave it drying out on a plate unless you enjoy cheese leather. Use it within a week or so, and remember that home cooks in Bulgaria often adjust salt by rinsing or soaking, not by complaining.

A simple home batch for the curious

Making sirene at home is not difficult, but it is a slow afternoon rather than a five-minute project. You need 2 litres of whole milk, 2 tablespoons of live natural yoghurt or buttermilk, a quarter teaspoon of liquid rennet diluted in a little cool water, and salt for brining. Use a clean pan and a thermometer if you have one.

Warm the milk to about 35C, stir in the yoghurt, and hold it there for half an hour. Add the diluted rennet, stir gently for ten seconds, cover, and leave it somewhere warm for 45 to 60 minutes until the curd sets with a clean break. Cut the curd into rough 2cm cubes, rest for ten minutes, then warm gently to around 38C to 40C for twenty minutes, stirring occasionally. Drain through muslin for a few hours, press lightly, then break the curd into pieces, salt to taste, and pack into a jar. Cover with brine made from 20g salt per litre of boiled, cooled water. Leave it in the fridge for a day before eating.

Home-made sirene will be softer and less uniform than a shop tub. That is part of the charm. Eat it within a week.

Three weeknight uses that are not banitsa

First, the five-minute shopska-ish salad. Chop cucumber, tomatoes, peppers and a little onion, crumble over a generous handful of sirene, and dress with sunflower oil, a splash of vinegar, salt and black pepper. In winter, cherry tomatoes work better than pale salad tomatoes. This is lunch, side dish or late-night fridge raid.

Second, sirene eggs on toast. Soften sliced leeks or spring onions in butter, add beaten eggs, and cook gently. Fold in crumbled sirene off the heat so it stays in soft pockets rather than melting into nothing. Pile onto sourdough toast and add black pepper. The cheese brings the salt, so taste before you reach for the shaker.

Third, a sheet-pan pepper bake. Halve peppers, add cherry tomatoes, garlic and a little oil, and roast until soft and blistered. Crumble sirene over the top, return to the oven for five minutes, and finish with parsley or dried mint. It works alongside roast chicken, as a vegetarian main with bread, or as the thing you make when the fridge looks empty but the cheese drawer does not.

Sirene is not a luxury ingredient. It is a working cheese, and that is exactly why it belongs in a British kitchen. Buy a tub, keep it in brine, and let it become ordinary. That is when it starts to feel like home.
