Heat the stock and keep it warm while preparing risotto.
In the Stainless Steel Saucier / Chef's Pan, heat 1 Tbsp (15ml) each of butter and the olive oil on medium low, add the onion, celery, and garlic. Gently cook for about 15 minutes without colouring.
In a separate pan, add the remaining olive oil and sauté mushrooms until tender and juices evaporate, about 5 minutes.
Add the rice and turn up the heat to medium. The rice will now begin to lightly fry, keep stirring. After a minute it will look slightly translucent. Add the wine and keep stirring.
Once the wine has cooked into the rice, add a ladle of hot stock and salt.
Turn down the heat to a simmer, continue adding a ladle of stock one at a time, stirring each ladleful to be absorbed before adding the next. This will take around 20- 25 minutes.
Continue adding stock until the rice is soft but with a slight bite. Taste for seasoning.
Remove from the heat add sautéed mushrooms, remaining butter and Parmesan. Stir. Place a lid on the pan for 2 minutes.
Sprinkle with parsley and serve hot.
