Break the cauliflower into small florets. Put into a steamer and steam over a high heat for 4–5 minutes until the thicker stalks are tender but the cauliflower still has a firm texture.
Sift the flours into a large mixing bowl and stir in the salt and spices. Make a well in the centre of the flour mixture and add the garlic, egg and fizzy water. Beat slowly with a wooden spoon to draw in the flours to make a smooth batter. Stir in the steamed cauliflower and, using the spoon, mash the cauliflower up into small pieces then add the coriander and mix in well.
Heat enough oil in a large frying pan to deep fry the fritters over a medium heat until hot. Spoon a couple of large spoonfuls or a few small spoonfuls, depending on the size of fritters you want, into the pan and cook for 1–2 minutes on each side or until golden. Remove from the pan with a slotted spoon and put on a pile of kitchen paper to remove any excess oil.
Repeat with the remaining batter, keeping the cooked fritters warm. Serve hot with the Coriander Yogurt.
