Broiled London Broil With Purple Plum Sauce - cooking recipe

Ingredients

2 lb. London broil
2 Tbsp. red wine vinegar
3 Tbsp. cooking oil
1/2 tsp. crumbled oregano
1/4 tsp. dry mustard
1/4 tsp. each: salt and coarsely ground pepper
1 lb. can purple plums
1 Tbsp. light brown sugar
1 Tbsp. lemon juice
1/2-inch fresh ginger

Preparation

Score the steak quite deeply with a sharp knife all the way down its length on the diagonal, about every 1/2-inch.
Turn steak around and repeat, scoring in opposite direction, so score marks become little squares.
