Heat the fat in a frying pan until it is very hot (almost smoking). Meanwhile, pour the milk into a saucer or shallow dish and take two slices of thick cut bread and 'dunk' them on both sides in the milk. This prevents them from absorbing too much fat and keeps the middle of the bread nice and moist.

Place the bread in the frying pan (stand back - it sizzles!), leave for about 30 seconds, then check the underside to see if it's browning. Keep checking until it is golden brown (it's easy to burn if you're not careful) then turn the bread over and cook the other side in the same way. You will almost certainly find that you have to add more fat as you cook, since fried bread does absorb it quite a lot.
