1 (5 lb.) loin or rib pork roast
1/2 c. brown sugar, firmly packed
1 c. hickory flavored or plain catsup
2 tbsp. prepared mustard
2 tbsp. tarragon vinegar
1 tbsp. Worcestershire sauce
1/2 tsp. salt

Roast pork in 325 degree oven for 3 to 3 1/2 hours, until meat thermometer registers 185 degrees. Combine brown sugar, catsup, mustard, vinegar, Worcestershire sauce and salt in a saucepan; cook, stirring occasionally, until sugar is dissolved. About 1 hour before roast is done, baste with sauce. Continue to baste every 10 to 15 minutes. Serve with remaining sauce.
