Preheat oven to 180°C. Peel, quarter and core apples. Place in small saucepan with water and cook over gentle heat, covered, until softened, about 10 minutes. Remove from heat and set aside. Prepare quinces by removing skin and cores. Butter a large ovenproof serving dish (or individual dishes) and spoon fruit into dish. Make crumble topping by rubbing butter into flour in a mixing bowl until mixture resembles coarse breadcrumbs. Do not overmix. Add ginger (if using), brown sugar and almonds. Stir to combine. Scatter crumble topping over fruit mixture, place in oven and cook for 30 minutes until topping is golden brown. Source: My collection - Jeff Baker - J Bakers Bistro Moderne
