Two Cheeses, Two Very Different Jobs

They sit side by side on the supermarket shelf, both white, both brined, both salty, and both with names that sound thoroughly Mediterranean — yet feta and halloumi behave almost nothing alike in the kitchen. Swap one for the other and you will notice immediately: crumbled feta on a hot griddle turns to a soft, salty puddle, while halloumi holds its shape and browns like a steak. Understanding why they behave so differently makes it far easier to choose the right one for salads, grilling or baking.

Feta: Crumbly, Brined and Sharply Salty

Feta is a Greek cheese protected by PDO status, which means it must be made in specific regions of Greece from at least 70% sheep's milk, with up to 30% goat's milk allowed. That sheep's milk matters: it gives feta its rich, faintly gamey tang and its generous fat content. The curds are not pressed hard, so the finished cheese has an open, crumbly texture that breaks into shards rather than slicing cleanly.

It is matured and stored in brine, and that is where most of the saltiness comes from. Good feta is firm enough to cut but soft enough to crush between your fingers, and it tastes bright and lactic rather than merely salty. Because it lacks the stretching proteins that melted cheese relies on, feta does not melt the way cheddar or mozzarella does. It softens, releases moisture and keeps its distinct crumbly character.

Halloumi: Firm, Squeaky and Built for Heat

Halloumi comes from Cyprus, and its defining feature is that the curd is heated in whey before being shaped and folded, then stored in brine. That cooking step alters the protein structure so the cheese keeps its shape at high temperatures — it is the reason a slice of halloumi survives a hot frying pan without collapsing. Traditional versions use sheep's and goat's milk, often with a little cow's milk added; PDO halloumi must be at least 51% sheep's or goat's milk.

Texture-wise it is dense, springy and slightly rubbery when raw, with a distinctive squeak against the teeth. Cooked, the outside turns golden and crisp while the middle softens to something creamy and chewy. It is salty and mild, though quality varies enormously — some supermarket versions are far saltier and bouncier than a good artisan one.

Melting, Grilling and Baking: What Happens in the Pan

This is where the two cheeses part company most dramatically. Feta has no melt-and-stretch network, so heat simply makes it drier, softer and oilier at the edges; in a very hot oven it will slump and lose its shape entirely. That is not a flaw — it is precisely why baked feta works so beautifully, softening into a spoonable, salty block you can stir through tomatoes, chilli and olive oil.

Halloumi is the opposite. It has a high melting point, so it can be grilled, fried or barbecued directly on the bars. Dry-fry slices in a non-stick pan over medium heat for a couple of minutes on each side and they will colour deeply without sticking. Push it too far, though, and it turns tough and leathery. It also firms up again as it cools, so serve it hot.

Which Cheese for Which Dish

A simple way to remember it: feta is for scattering, halloumi is for slicing.

• Greek salad: feta, every time. Add a whole slab on top, drizzle with olive oil and oregano, and let it sit for ten minutes before serving.
• Watermelon or peach salads: feta's salt cuts through the fruit's sweetness; crumble it coarsely rather than finely.
• Spinach and filo pies: feta, crumbled and mixed with eggs and dill. Halloumi would go rubbery and heavy here.
• Barbecues and griddle pans: halloumi. Thread cubes onto skewers with peppers, or grill thick slices and squeeze lemon over them.
• Traybakes and roasting tins: both work, but differently — halloumi added in the last fifteen minutes keeps its shape, while feta crumbled over vegetables melts into the juices and seasons everything.
• Breakfast: halloumi fried with eggs, tomatoes and toast; feta crumbled over avocado or folded into an omelette.

Buying and Storing Notes for UK Kitchens

For feta, buy it in brine in a tub rather than the dry, pre-crumbled sort — the difference in flavour is considerable. Look for PDO on the label. Once opened, keep it submerged in its brine in a sealed container in the fridge and use it within a week or so; if the brine becomes cloudy, pour it away and cover the cheese with fresh salted water instead. If it is too salty for a particular dish, soak slices in cold water for twenty minutes. Feta freezes, but it becomes more crumbly afterwards, which suits baking better than salads.

Halloumi is usually vacuum-packed and keeps for weeks unopened. Once opened, wrap it well and refrigerate, using it within a few days. Pat slices dry before frying so they brown rather than steam, and if the salt level is fierce, soak them in cold water or milk for half an hour, then dry thoroughly. It can be frozen too, though it becomes slightly more crumbly once thawed. Buy both from a shop with a decent turnover, and you will taste the difference immediately.
