Duck with Wine

Season the cleaned duck inside and out with salt and sprinkle with black pepper. Braise the finely chopped onion in a little oil, add the finely chopped bacon, and shortly after add the duck cut into pieces. When the meat browns, add the sliced mushrooms. Pour in the wine and once it boils, add the tomato paste dissolved in a little warm water, the bay leaf and the thyme. Cover and leave on low heat for 45 minutes. If the sauce is thin, you can add a little butter and flour.
