Soak the porcini mushrooms in 250ml/9fl oz warm
water for 30 minutes. Cut the beef and pork into 1cm/1/2in dice.
Drain the porcini, reserving the
liquid. Squeeze the water out of the porcini and
chop. Strain the liquid.
Melt the butter in a
large pan over a medium-low heat. Add the shallots,
celery, carrot and porcini mushrooms. Increase the
heat to medium and sauté for about 5 minutes, or
until lightly colored. Stir in the parsley.
Reduce the heat and add the meat. Brown it lightly
on all sides. Stir in the flour, pour in the porcini
liquid, meat broth and wine, and season with salt
and pepper.
Stir, cover and simmer for about 2 1/2
to 3 hours, stirring occasionally, until the meat
begins to disintegrate and the sauce thickens. Serve
hot with fresh pasta.
