Pairing fruit with herbs is one of my not-so-secret weapons, and today’s combination is a favourite. The sweet blackberries cook down to become jammy, while the sage-speckled crumble adds a fragrant, earthy warmth. A good, buttery base is essential for any crumble bar, so bake it before adding the fruit to avoid a soggy bottom. I like to think of these as a bit of a farewell to summer and a welcome to autumn.
