Place the oil and half of the butter in a pan over a medium-low heat. Cook the leek, garlic and rosemary, stirring for 6-8 minutes, until soft.

Add the rice and gently fry it. Then add the wine and allow it to evaporate. Add the stock, a little at a time, stirring all the time, for 20 minutes or until the rice is firm (you might not use up all the stock). Add the cream and cook for a further 2-3 minutes.

Melt the remaining butter in a pan over a high heat. Cook the mushrooms and rosemary for 6-8 minutes, or until golden. Add the rice to the mushrooms, then add the diced Paglierina.
