Reduce a can of tomatoes with a little salt and sugar. Meanwhile boil the pasta water. While you are waiting watch your collection of Roberto Baggio commercials.
Soften the cauliflower flowers in the water, only for a minute or two, don't cook them through. Transfer the flowers to the tomato sauce and then cook the spaghetti with the inevitable cauliflower residues until 30-40 seconds before done, add the pasta to the tomato sauce and cook until you know what.
Eat hot whilst thanking god or evolution for cauliflower.
