Preheat oven to 350
Blend apples, prunes, apricots, tomato paste, cornflour, and soy sauce in a food processor until smooth..
Spice the meat well with coarsely ground black pepper.
Place meat into a small, but deep, roasting dish, with about 1 cm spare at either end and round the sides. It should almost fit like a glove!
Pour over the sauce, cover with foil and roast for 1 1/2 hours. (If the piece of meat is larger then a little longer).
Reduce the heat to 325 Decg. F , turn the meat over and continue to roast for 40 minutes uncovered.
Turn meat over again and roast for a further 30 - 40 minutes, basting every 15 minutes until a rich golden-brown glaze forms around the meat.
Serve with your favourite vegetables or potato kugel. Great kugel recipe on page 30 in the Shabbat section of 'Celebrating with the Kosher Butcher's Wife'.
