Steak Tartare
-------------
1 lb. sirloin or tenderloin steak, freshly ground twice
1/2 c chopped onion or green onion
1 tbsp ice water
Egg yolks
Salt & freshly ground pepper
Garnishes: chopped onion, capers, freshly grated horseradish, and chopped 
           parsley

Lightly mix the steak with the chopped onion and water. (Water makes it 
fluffy.) Pile on individual plates. Make an indentation in the center of 
the meat and slip in a raw egg yolk. Sprinkle with salt & pepper. Serve 
with garnishes. Makes 4 servings.
