Preparation - Place the roast in a shallow baking pan with a small amount of water. Roast, uncovered, at 325º for about 2 hours. About 30 minutes before roasting time is complete, in a saucepan, combine cherry jam or preserves, corn syrup, vinegar and spices. Heat to boiling, stirring frequently. Reduce heat to simmer and cook 2 more minutes. (this step could be done in a microwave oven instead). Add the toasted almonds(if using). When the meat has roasted for 2 hours, remove it from the oven and spoon enough cherry sauce over the roast to glaze. Return to the oven for about 30 more minutes, or until a meat thermometer reads 170º. Baste the roast with sauce several times during last 30 minutes. Serve the remaining cherry sauce with the roast.
