Chicken and porcini casserole

I love using porcini mushrooms. There's a certain richness that it generates in stews and soups, that you can't get from normal button/chestnut mushrooms. For this recipe, place 20g of porcini mushrooms in a bowl and cover with 1/4 cup of boiling water. Leave for 5 minutes until the mushrooms are fully hydrated. Lightly toss 1.5 kg of chicken pieces in 1/4 cup of seasoned plain flour to coat. Heat oil in pan and cook the chicken over medium heat in batches until browned. Set aside. Add 1 chopped onion and 2 cloves of chopped garlic to the pan and cook for 3-5 minutes. Stir in 1/4 cup of chicken stock. Return the chicken to the pan with the porcini mushrooms and the liquid. Add 1/3 cup of white wine, 1 can of chopped tomatoes, 1 tbsp of balsamic vinegar, 3 sprigs of thyme and 1 bay leave. Cover and simmer for 30 minutes. After 30 minutes, add 300g of field mushrooms. Cook, uncovered for 20 minutes until the sauce thickens. Serve with pasta.
