Sprouts have a sweet, nutty flavour, and taste great raw or cooked. Sprouts do cook quickly and can become bitter and mushy when overdone, so do make sure you watch them carefully! Although they should be firm, a sharp knife should still easily slide into the stem. Brussels sprouts are a classic accompaniment to traditional Christmas dinner – experiment with a crisp Parmesan crust, cook in brown butter and top with a garlicky crumb, or dot with a Marmite butter even the haters will love. If you have leftover sprouts after Christmas, bake into this sprout, blue cheese and walnut puff pastry tart.
