Put all the ingredients in a blender and blend till smooth. Put into a glass jar and let sit for a day.

Build a charcoal fire. Put cast iron pizza 'stone' over the fire. Liberally oil. Pour chickpea batter over and tilt the pan until all the runny batter is in contact with cast iron. Cook till crispy, then flip and finish cooking. It usually takes me 2 or 3 minutes.

Lift pan out of the fire and serve at table. I usually drizzle olive oil on top and sprinkle flake sea salt.
