Step 1

Preheat the oven to fan 160C/ conventional180C/gas Butter a 1.5 litre ovenproof pie dish.

Step 2

Peel, core and slice the apples. Halve, stone and quarter the plums. Put the apples in a pan with the lemon juice, sugar and 1 tbsp water. Bring to the boil, then cover and cook gently for 5 minutes. Add the plums and cook for a further 5 minutes.

Step 3

Turn the fruit into the prepared dish. Tip the flour and cinnamon into a bowl, add the butter, cut into small pieces and rub in with your fingertips. Stir in the sugar, then add the egg and milk and mix lightly to a soft batter (this can be done in the food processor).

Step 4

Drop tablespoonsful of the batter over the fruit, leaving gaps where the fruit peers through, then scatter over the nuts. Bake for 25-30 minutes until the topping has a crisp brown crust.
