Beef in Pepper Sauce (Zilzil Alecha ? Ethiopia)

Serve over hot cooked rice.

1 (2 pound) beef boneless sirloin or top
    loin steak, 3/4 inch thick
2 medium red bell peppers, coarsely chopped
2 jalape?o peppers, seeded and chopped
3 cloves garlic, cut into fourths
1/3 cup dry white wine
1 tablespoon chopped gingerroot
1 1/2 teaspoons salt
1 teaspoon ground turmeric
1/2 teaspoon ground cardamom
1 tablespoon butter or margarine
1 tablespoon vegetable oil 
2 medium onions, chopped
1 medium red pepper, cut into 1/2-inch strips

Trim fat from beef; cut beef across grain into 1 1/2 x 1/2-inch strips.

Place chopped peppers, jalape?o peppers, garlic, wine, gingerroot, salt, turmeric and cardamom in blender container. Cover and blend on medium-high speed, stopping blender occasionally to scrape sides, until mixed, about 45 seconds.

Heat butter and oil in 12-inch skillet until hot. Cook and stir beef over medium-high heat until all liquid from beef is evaporated and beef is brown, about 15 minutes; remove beef with slotted spoon.

Cook and stir onions and pepper strips in remaining oil mixture over medium heat until tender.

Add blended pepper mixture and beef. Heat to boiling; reduce heat. Simmer uncovered, stirring occasionally, until beef is hot and sauce is slightly thickened ? about 10 minutes.

Yields 8 servings.
