Clean the cauliflower, cut into even florets and wash. Briefly blanch in boiling salted water, remove with a slotted spoon, drain well.
Mix the flour, cheese, curry and a pinch of salt. Stir in egg yolk, butter (liquid) and beer. Beat the egg white until stiff and fold into the batter.
Heat the frying fat in a deep fryer to 180 degrees. Dip the cauliflower florets one after the other in the batter and then fry them in the hot fat until golden brown. Lift the vegetable pieces out of the fat with the skimmer and let them drain on kitchen paper.
