In the far north, across Swedish Norrbotten and Finnish Lapland, coffee comes with cheese in the cup. Leipäjuusto, a mild, squeaky cheese baked or grilled until spotted brown (called kaffeost or 'bread cheese'), is cut into cubes and put in a cup, often a carved wooden kuksa, then hot black coffee is poured over. Sámi reindeer herders and Tornedalen farmers have made it this way for generations; it is a fireside or mid-morning drink on a cold day, and in some families a little sugar or a slice of dried reindeer meat goes in as well. The cheese warms through, softens slightly and soaks up the coffee, so you drink the coffee and then spoon out the warm, chewy, milky cubes. The common mistake is using a soft or melting cheese: it collapses into strings. Use proper leipäjuusto or halloumi, which keep their shape. It is ready when the cubes are hot to the centre, about 2 minutes, and slightly puffed. Strong coffee means real caffeine here, so it is an adult drink. Leipäjuusto is sold in Nordic shops; halloumi is the nearest substitute. Chef's tip: warm the cheese on a dry pan first for extra browned flavour.
