This tastes as good as it looks!
4 large peaches (or 5-6 small)
1 cup blueberries
1/4 lemon, juiced
1 tbsp demerara sugar
1 tsp cornflour/cornstarch
1/2 cup flour (I used wholemeal self-raising)
1/2 cup oats
1/4 cup demerara sugar
pinch sea salt
80g (about 3/4 stick) cold butter, cut into pieces
1/4 cup boiling water
Preheat oven to 210 degrees C.
In a large bowl mix peaches, blueberries, lemon juice, sugar and cornstarch. Place fruit mixture into a baking dish (I used a pie dish).
To make the topping: In a bowl combine flour, oats, sugar and salt and then rub in cold butter pieces with hands until mixture forms a crumbly like texture like sand -- leaving some lumps is ok. Stir in hot water a little at a time until mixture just combines, don't overmix. Drop spoonfools of topping over fruit mixture and bake in the oven for about 25 minutes or until topping is golden brown. Note: I didn't pre-cook my fruit as I wanted it to have some texture and not be too soft.
