Roast fennel and aubergine paella

I am a massive fan of Spanish food, and paella is my all-time favourite Spanish dish. I love the fact that there are so many regional variations, and like an Italian risotto, you can tweak it to suit your taste or mood. Make it vegetarian one day or add meat or seafood another time. For me, the best part is the layer of toasted rice at the bottom of the pan – it’s called ‘socarrat’ in Spanish, and is considered a delicacy.
