Preheat the oven to 200÷C/400÷F/gas 6. Put your porcini mushrooms in a bowl and pour over just enough boiling water to cover them (approx. 150ml/5½fl oz). Put to one side to soak for a few minutes. Heat a saucepan big enough to hold all the ingredients, and pour in a splash of olive oil. Season the chicken pieces with salt and pepper and brown them gently in the oil. Strain the porcini, reserving the soaking water, and add them to the pan with the garlic and fresh mushrooms. Add the wine, with the strained porcini soaking water, and turn the heat down. Simmer gently until the chicken pieces are cooked through and the wine has reduced a little.
