Turn up the heat, pour a little of the reduced wine into the pan and scrape the bits off the bottom with a wooden spoon, then put in the chicken and the bacon, keeping a few bits of the latter back as garnish. Pour over the brandy and set it alight, then, when the flames have gone out, add the rest of the wine and thyme leaves. Bring to the boil, turn down the heat, cover and simmer gently for an hour.
