To stew capons in white broth Recipe
Ingredients:4 beef marrowbones
1 whole, oven-ready chicken
1 sprig of rosemary, tied together
2 onions, sliced into rings
2 blades mace
100g pitted prunes
1 handful flat-leaf parsley
60ml verjuice (or white wine vinegar)
thin white bread, toasted
Method:Begin with the beef stock. Place the marrowbones in a large pot and cover with 4l of water . Bring to a simmer and skim off all scum and fat from the surface. Now bring to a boil and continue boiling for about 2 hours, or until the liquid has reduced in volume to about 1.5l. Take off the heat and strain the stock into a bowl.
Arrange a layer of sliced onion in the base of a large stockpot or casserole dish. Sit the chicken on top then add the remaining onions and the rosemary. Add in enough of your stock to come half way up the sides of the chicken then add the mace. Bring the mixture to a simmer. Cover and cook for about 40 minutes then add the parsley, verjuice and prunes.
Season to taste with salt the continue boiling for about 10 minutes more, uncovered, or until the prunes are tender. Arrange the toasted bread on a serving dish. Remove the chicken from the pot and cut into serving pieces. Arrange these on top of the toasted bread pieces. Remove the prunes from the stock and use to garnish the birds.
Pour over a couple of ladlefuls of the stock and serve.
