Place roast on a rack in a shallow roasting pan. Insert an oven-going meat thermometer into center of roast. Roast in a 325 degree F oven for 1-1/4 hours to 1-3/4 hours or until the thermometer registers 150 degrees F.

Meanwhile, for glaze, in a 2-quart saucepan combine rhubarb and apple-cranberry juice concentrate. Bring to boiling; reduce heat. Simmer, covered, for 10 to 15 minutes or until rhubarb is very tender. Strain mixture into a 2-cup liquid measure, pressing out liquid with the back of a spoon; discard pulp. If necessary, add enough water to liquid to equal 1-1/4 cups.

In the saucepan stir together cornstarch and the cold water. Stir in rhubarb liquid. Cook and stir over medium heat until thickened and bubbly. Cook and stir for 2 minutes more. Stir in honey, mustard, and vinegar. Heat through.

Brush some of the glaze onto the meat for the last 30 minutes of roasting. Cover meat with foil and let stand 15 minutes. The temperature of the meat after standing should be 160 degrees F. Reheat remaining glaze; serve with meat.
