What is halloumi made from?

Traditional Cypriot halloumi is made from sheep and goat milk, sometimes with a little cow milk. The milk is curdled, the curds are cooked in their own whey to set the structure, and then the cheese is salted and stored in brine. That cooking step gives halloumi its high melting point, which is why you can fry or grill it without it losing shape. Australian made halloumi often uses more cow milk, and some is made from cow milk alone. Both work well in a cafe kitchen.

Should halloumi be soaked or blanched before cooking?

Only if the cheese is too salty for the dish. A thirty second blanch in fresh boiling water draws out some of the brine, which helps when halloumi sits next to other salty things like cured pork, anchovies or capers. Most of the time you don't need to, and blanching can leave the cheese tasting flat. Taste it raw before you decide. The squeak isn't affected either way, because it comes from the protein structure and not the salt.

Why does halloumi go rubbery?

Usually because it was cooked too low and slow, which breaks down the protein structure that makes it springy. It also happens when cooked halloumi sits too long, because the proteins tighten again as the cheese cools. And old cheese, or cheese that's been frozen and thawed, is already damaged before it hits the pan. Buy it fresh, cook it hot and serve it straight away.

Can halloumi be cooked from frozen?

It can, but it's noticeably worse. Freezing damages the protein structure that produces the squeak. Thawed halloumi also releases more water as it cooks, so the surface doesn't caramelise properly and the flavour is diluted. For a cafe pass, use fresh halloumi from a brined block. Unopened halloumi keeps in the fridge up to the date on the pack, so freezing is rarely necessary. Once opened, keep it in its brine and use it within the time the label gives, often three to seven days. La Casa gives 7 days from opening for its halloumi.

Is halloumi vegetarian?

Most commercial halloumi is vegetarian, including most Australian brands and Cypriot imports. Traditional halloumi was sometimes set with animal rennet, but most modern producers use vegetarian rennet. If your menu calls a dish vegetarian, check the back of the pack. The label will say whether the rennet is vegetarian or microbial, and both are fine for vegetarians.

What flavours pair well with cooked halloumi?

The classic is warm honey and fresh thyme, added the moment the cheese comes off the pan. Lemon zest, chilli honey, dukkah, za'atar and pomegranate molasses all work too, because the caramelised surface and salty inside stand up well to sweet and sour flavours. Whatever you use, keep it light. People ordered the halloumi, so let the cheese carry the plate.

The cheese that squeaks

Q: Why does halloumi squeak?

It comes down to the protein structure. Unlike most cheeses, halloumi isn't aged, and the milk proteins inside it stay in long, tightly bound strands that survive heat without breaking down. When you bite a hot piece, those springy strands catch and slip against your teeth, and that's the squeak. A short, hot cook keeps that structure intact and the squeak audible. A long, low cook breaks it down and the cheese goes quiet.

The answer

Yes, halloumi should squeak

The squeak is the test. If a piece of halloumi squeaks against your teeth, it's fresh, it was cooked hot and fast, and it got to the table before it cooled. If it doesn't, one of those went wrong. Usually the last one.

Halloumi that doesn't squeak has lost the dish. Maybe the cheese was past its best, maybe it was cooked too long, or maybe it sat on a warm pass while the rest of the order caught up. Very few things in a kitchen give you a clear yes or no like this, so if halloumi is on your menu, cook towards the squeak.

The squeak

What makes halloumi squeak

Halloumi isn't aged, and the milk proteins inside it form long, tightly bound strands that survive heat without breaking down. When you bite a hot piece, those springy strands catch and slip against your teeth, and that's the squeak. Most cheeses melt or soften before they get the chance. Halloumi has a high melting point, so it doesn't.

That's why the cook matters more than the cheese's chemistry. A short, hot cook builds a golden crust and leaves the structure inside intact. A long, low cook breaks the proteins down, and the squeak goes with them.

The cheese

Buy the right cheese

Whether your halloumi squeaks starts with what you bought. Real halloumi is brined and semi hard, made from sheep and goat milk (sometimes with cow milk too), and sold in vacuum packs sitting in its own salty liquid. Cypriot halloumi is the original, and the imported blocks are very good. Several Australian producers now make cheese that does just as well on a cafe pass.

Avoid anything labelled halloumi style or grilling cheese. It's usually built on a different protein structure, doesn't hold its shape under heat the same way, and doesn't squeak. It's cheaper, and you'll see why on the plate. We'd pay the extra every time.

The cook

Slice thick, pan hot, ninety seconds a side

Cut slices eight to ten millimetres thick. Any thinner and the cheese dries out and goes leathery before the surface caramelises. Any thicker and the centre stays cold while the outside burns. Use a sharp knife on cold, well drained cheese. A blunt knife on warm cheese tears the edges and leaves the slices uneven, and uneven slices cook unevenly.

Get the pan hot: medium high heat and a thin film of neutral oil like grapeseed or canola. Never butter, because butter browns and burns before the halloumi is ready. Pat the slices dry with a clean cloth before they go in. Ninety seconds a side is our working number, a little less for thinner cuts. You want a deep, even golden colour and a faint sizzle. When you flip a slice and see that crust, it's done.

The window

The three minute rule

Halloumi has a squeak window of about three minutes. Off the pan, the proteins start to tighten again as the cheese cools, and the squeak fades into a flat, rubbery chew. By five minutes it's gone. By ten the cheese is closer to chewy plastic. Busy kitchens miss this more than anything else, and it's why the same dish is great at table one and disappointing at table two.

So cook halloumi to order, plate it last and get it out fast. Don't hold it under a warmer or cook it ahead. If your service can't work that way, take it off the menu. Get it right and customers order it again next visit.

The brine

To blanch or not to blanch

Some kitchens blanch halloumi for thirty seconds in fresh boiling water before frying, to draw out some of the brine. That makes sense if the cheese is too salty for the dish, especially next to cured pork, anchovies or capers. The catch is that the brine is part of why halloumi tastes good, and pulling it out can leave the cheese flat.

Our advice: taste it raw first. If the salt sits well, fry it as is. If it overpowers the dish, blanch briefly and pat dry. The squeak survives either way, because it comes from the protein structure and not the salt. Overcooking is what kills it.

The pairings

Honey, thyme, and what to put on it

The caramelised surface holds onto whatever you finish halloumi with, and its salty, springy inside stands up well to sweet and sour flavours. The classic pairing is still the best: warm honey and fresh thyme. Drizzle the honey over the slices the moment they come out of the pan and scatter the thyme on top. The heat left in the cheese draws the oil out of the thyme and into the honey.

From there you've got plenty of room. Lemon zest cuts the salt. Chilli honey adds heat and keeps the sweetness. Dukkah or za'atar suits halloumi's eastern Mediterranean roots. Pomegranate molasses gives a darker, deeper finish. Whatever you choose, go easy on it. People ordered the halloumi, so keep the topping light and let the cheese carry the plate.
