The crumble can be made by hand if you don't have a food processor. Place brown sugar, flour and Gregg's Ground Cinmon into a mixing bowl and rub in the butter with your fingertips until the mixture resembles breadcrumbs. Stir through the cornflakes.
Replace apples with fresh pears or drain a can of Wattie's Pears, dice and mix with the boysenberries.
Any extra crumble mixture can be put into an airtight container and frozen until required. No need to thaw just sprinkle frozen crumble mix over your favourite fruit combination.
