Preheat the oven to 220°C/fan 200°/gas mark 7 and line a baking tray with non-stick baking parchment.
Mix together the gram (chickpea) flour, garlic powder, onion salt and water and mix to form a thick batter. Dip each floret into the batter so that it is fully coated and place on the lined baking tray.
Bake in the oven for 15 minutes, then drizzle over the hot sauce, making sure all the florets are coated. Return to the oven and bake for a further 20 minutes until crispy.
