This is a recipe that I had neglected for far too long. I made them the other night for the first time in a few years and they were just as good as I had remembered. I still have some of the cucumber sauce in the fridge and I’m putting it on everything. Yum. I actually used plain yogurt that I had set in a strainer to drain the liquid out in place of the sour cream.
1 medium onion, cut into chunks
2 garlic cloves
2 Tbsp sugar
1 Tbsp ground mustard
1/2 tsp ground ginger or 2 tsp minced fresh ginger root
1-1/2 tsp pepper
1/2 tsp cayenne pepper
1/2 cup soy sauce
1/4 cup water
2-3 pounds boneless sirloin, cut into 1/4 inch thick slices
Cucumber Sauce:
1 medium cucumber, peeled, seeded and cut into chunks
4 garlic cloves
1/2 tsp salt
1/3 cup cider vinegar
1/3 cup olive or vegetable oil
2 cups (16 ounces) sour cream
8-10 pita breads, warmed and halved
Thinly sliced onion
Chopped tomato
In a blender of food processor, place the onion, garlic, sugar mustard, ginger, pepper and cayenne; cover and process until onion is finely chopped. Add soy sauce and water; process until blended. Place the beef in a large Ziploc bag. Add marinade. Seal bag and turn to coat; refrigerate for several hours or overnight.
For sauce, combine the cucumber, garlic and salt in a blender or food processor; cover and process until cucumber is chopped. Add vinegar and oil; process until blended. Transfer to a bowl; stir in sour cream. Refrigerate until serving.
Drain and discard marinade. Grill beef, covered, over medium-hot heat until meat reaches desired doneness. Place beef in pita halves. Top with cucumber sauce, sliced onion and chopped tomato. Refrigerate any remaining sauce.
