Halloumi is a semi-hard, unripened cheese traditionally made from a mixture of goat's and sheep's milk, and sometimes cow's milk. Its origins trace back to Cyprus, where it has been produced for many centuries. The cheese is known for its distinctive layered texture and high melting point, allowing it to retain its shape when grilled or fried.

The earliest references to Halloumi date back to the Medieval Byzantine period, with documentation suggesting its production in Cyprus in the 12th century. The name "Halloumi" is derived from the Greek word "αλμυρός" (almirós), meaning salty, reflecting its flavor profile.

Production involves heating milk and adding rennet to curdle it. The curds are then drained and pressed into molds. Halloumi is traditionally folded into a half-moon shape and stored in its own whey with added salt, which acts as a preservative. Fresh mint leaves are often included in the storage process to enhance flavor, though this practice varies.

Halloumi's role in Cypriot culture is significant. It is a staple in the Cypriot diet and is commonly served grilled, as a side dish, or in sandwiches and salads. It also features in celebrations and traditional recipes, reinforcing its status as a cultural symbol.

Worldwide, Halloumi gained popularity for its resilience to melting, making it suitable for grilling and frying. The European Union granted Halloumi Protected Designation of Origin (PDO) status in 2021, recognizing its unique regional production in Cyprus.

Despite its historical and cultural roots, Halloumi faces challenges, including trademark disputes and debates over the use of cow's milk. However, its popularity continues to grow, particularly in Europe and the Middle East.
