Bring the milk to the boil in a saucepan with the sugar, butter, pinch of salt and the lemon zest
Once boiling, add the flour and work the dough with a wooden spoon. When the dough is smooth and it doesn’t stick to the sides, remove the saucepan from the heat and leave to cool
When the dough has cooled down, add the eggs one at a time and combine thoroughly. Add the ratafia (or liqueur of your choice) and mix into the dough
Leave the dough to rest for half an hour
Heat the oil in a deep frying pan and take a tiny portion of the mixture with a metal spoon. Work the mixture into a ball with the help of another spoon
Drop the ball carefully into the oil and fry the bunyol until golden. The bunyols will double in size. Be careful not to heat the oil too much, otherwise the bunyols will be raw inside when cooked on the outside. It should be a gentle fry
Drop the other bunyols into the pan being careful not to overcrowd it. The bunyols will turn on their own once each side is cooked, but keep an eye to ensure they are golden all over
Once the bunyols are cooked, remove them from the frying pan and place them on kitchen paper to drain. When they are still ever-so-slightly oily, roll them in sugar
Leave to cool for at least an hour before eating them. If you try them while warm they will seem undercooked!
