First remove the outer leaves and the stem of the cauliflower. Remove the florets with a knife and cut the larger ones into 2 or 3 smaller pieces to obtain florets of the same size. Rinse them under water, dab with a clean kitchen towel and put in the fridge.
For the batter: Put flour, curry, paprika and baking powder in a bowl and mix well with a whisk. Then add very cold beer drop by drop and mix to a smooth and homogeneous batter. Put in the fridge.
