Success! I've just used Doves Farm gluten free self raising flour to make the best bannock bread yet. I followed Liam's approach for his rum and raisin bannock.
Three parts flour
One part dried milk powder
One teaspoon allspice
One teaspoon cinnamon
Two teaspoons of minced raisins
A dash of sunflower oil
I mixed the above with enough water to make a thick batter, and dropped a tablespoon of the mixture into the pan. I flipped the bread over once the underside was done and continued cooking until it sounds hollow when tapped with the spoon. Unfortunately I didn't have any rum knocking around the house but the result was delicious all the same! The above quantity will make two breads.
