At the Greek Church I'm a member of they use virgin olive oil, not butter. They heat the oil, take the cold kefalotere cheese, run it under water then put it in a container of flour and coat all sides. Then place it in the frying pan with the heated olive oil and fry it until the bottom is golden brown and the cheese looks like it is starting to melt. Then turn it over and repeat. Remove it from the heat, add a shot of cognac or a good quality brandy, light it, then squeeze the lemon high over the flaming cheese, don't burn your arm. The flame will die down rather fast... serve it with warm pita bread.
