Sweet, smoky and just the right amount of spicy, this roasted purple cauliflower is an easy-to-make showstopper. Searing first builds deep flavour, while roasting keeps it tender with a slight bite. The harissa honey butter adds warmth and richness, balancing beautifully with cooling Greek yoghurt and fresh coriander. A final squeeze of lemon ties it all together–simple, striking, and packed with flavour.
