While the duck is baking, you can make the risotto. Boil the stock and dice the onion and garlic. Put a medium saucepan over mnedium heat and heat up the olive oil. Saute the onion and garlic for a few minutes with a pinch of salt, then add the rice. Stir for a few minutes, then add the wine. When the rice absorbed all the wine, add half a cup of the boiling stock. Stir until this is absorbed by the rice too, then add another half cup of the stock.
