Hull the strawberries, half them depending on their size. Top and tail the gooseberries then tip into a large bowl and toss with the caster sugar.
Cover the bowl and leave for at least 2 hours to macerate (overnight is okay). In the fridge
Meanwhile make the crumble topping by mixing the flours and sugars together in a large mixing bowl. Add the cinnamon, ginger and salt.
Rub the butter into the dry ingredients until it starts to clump together. The crumble topping doesn’t need to be very fine breadcrumbs, a shaggier texture works better. Set aside until the fruit is ready.
Pre-heat the oven to 190°C / 170°C fan assisted / gas mark 5 / 375°F.
Drain the fruit and measure 100g of the macerating liquid into a small bowl. Stir the cornflour into the juices until smooth. Pour the juices back over the fruit and toss together, along with the ginger, cinnamon and vanilla extract.
Pour the fruit mixture along with all the juices into the bottom of a baking dish.
Cover the fruit evenly with the crumble topping, sprinkle over the chopped almonds then place in the oven for 40 minutes. The crumble is ready when the topping is golden brown and the fruit is bubbling up from within.
Allow the crumble to rest for at least 15 minutes before serving.
