Saffron risotto

Heat the stock in a pan over a very low heat – have a ladle at the ready. Melt the butter and olive oil in a high-sided, non-stick frying pan. Add the onion and a large pinch of salt, then cook, stirring, for 5 mins until softened and fragrant but not colouring. Tip in the rice and coat in the oil and butter, cooking for a few mins until beginning to toast. Pour in the wine and cook, stirring, until it’s absorbed. Add the saffron and begin to add the stock, a ladle at a time, stirring continually. Add more stock as it’s absorbed. After 25-30 mins, all the stock should be absorbed and the rice should be creamy and al dente.

Add the Parmesan and stir until melted. Turn off the heat and stir in the egg yolk. Season and serve with a peppery rocket salad, if you like.
