For the peaches, place verjuice, 2 cups (500ml) water and sugar in a saucepan and stir over low heat until sugar dissolves. Increase heat to high and boil for 20 minutes or until liquid is syrupy and has reduced to 3 1/2 cups (875ml). Place peaches, cut-side down, in a large wide-based saucepan or a deep fry pan. Pour sugar syrup over peaches, then place a round of baking paper on the surface to keep peaches immersed. Simmer gently over low heat for 12-15 minutes until tender. Using a slotted spoon, transfer peaches to a baking tray and peel when cool enough to handle.

Cook until golden brown on one side, then turn and cook for a further minute. Keep warm while you repeat with remaining butter and batter.
