Onion Bhaji's are easier to make than you might think. This recipe came from the Uncaged website.
4oz gram flour
Mix all the ingredients except the water together, then add the water gradually until you have a thick batter (you may not need to use it all).
Deep fry in batches for 2-3 minutes, until golden brown.
These are good served on a bed of shredded lettuce with a wedge of lemon.
