This tart is a real treat for autumn: melt-in-the-mouth thanks to the homemade compote, fruity with its slices of fresh apple and irresistible with its layer of cinnamon-flavoured crumble. It also has the advantage of being vegan and gluten-free, which means everyone around the table can enjoy it, even those with food intolerances. It's a simple recipe that anyone can make and that's sure to impress.
