1/3 c. sour cream
2 Tbs. mayonnaise
½ tsp. garlic powder
¼ tsp. celery salt
2 Tbs. chili sauce
1 Tbs. lime juice
½ to 1 tsp. crushed red pepper flakes
¼ tsp. salt
1 flank steak (1 to 1 ½ pounds)
In a bowl, combine the sour cream, mayonnaise, garlic powder, and celery salt; refrigerate until serving. Combine the chili sauce, lime juice, pepper flakes and salt; brush half on one side of steak.
Broil 6 inches from the heat for 10 minutes. Turn steak; brush with remaining mixture. Broil 6-10 minutes longer or until meat reaches desired doneness. Let stand for 5 minutes. Slice into thin strips across the grain. Serve with the sour cream sauce.
