Cut the cauliflower in medium chunks, and steam or boil for a few minutes, until soft but firm. You should be able to stick a fork in it, but it shouldn't break or crumble when you do it.
Beat the egg whites in a mixer, until fluffy but firm.
Add the egg yolks, salt and pepper, and some flour, to form a slightly thick liquid.
Heat the oil in a frying pan. Soak a chunk of cauliflower in the egg mixture, and fry until golden, turning around. You may need to add some more of the egg mix. Use a spoon or two, to keep the egg around the cauliflower (it tends to spread to the sides instead of sticking around the vegetable).
Repeat with every piece of cauliflower.
Put in a dish covered with paper towel, to absorb the oil.
Eat hot, or at room temperature.
