Preheat the oven to 190°C/375°F/Gas mark 5.
Arrange the peaches in a glass dish measuring about 20cm/8in in diameter. Mix together the maple syrup with half of each of the ground nutmeg, cinnamon, cloves and ginger. Drizzle the mixture over the peaches, making sure that each piece of fruit is well coated. Allow to stand for 10–15 minutes.
In a mixing bowl, combine the flour, milk and egg whites and blend to mix. Pour carefully over the top of the fruit, then sprinkle with the other half of the spices.
Bake, uncovered, in the oven for 45–50 minutes until the topping is cooked and golden. Serve hot with cream or ice cream.
