And if you’re in need of a baking recipe that makes the seasonal fruit shine, look no further than this apple oat crumble from the Institute of Culinary Education. In place of butter, the oat crumble topping uses refined coconut oil. The filling consists of apple slices from four Granny Smiths combined with salt, sugar, cornstarch, cinnamon, and apple juice. Make the filling: In a large bowl, whisk together the salt, cornstarch, cinnamon, sugar, and apple juice. In a separate bowl whisk the oil, syrup, and salt.
