Mix the dry ingredients together, the add the water quickly & continue to stir. Spread batter on a pie plate & put in a preheated oven heated to 220ºC . Bake for 20 minutes. Cut in pieces & serve hot or cold. Excellent with mint tea. **MARKS NOTE: The recipe doesn't say when the blueberries should be added, I would assume that it would be before mixing in the water.
