Lemon Potatoes

8 medium potatoes
1/4 cup margarine
4 Tbsp vinegar
1/2 tsp lemon juice
cornstarch to thicken

Boil potatoes until almost soft (until a fork almost pierces through them). Drain potatoes and place them back into the hot pot to allow steaming which will reduce moisture, approximately 30 seconds to 1 minute. Place potatoes in roaster. In a pot on stove, combine remaining ingredients - enough cornstarch to thicken.  Remember to break down cornstarch before adding, with a small amount of water.  Place mixture over cooked potatoes in roaster. Bake at 325 F for 25 minutes.
