10 ounces fine quality marbled beef, trimmed of gristle, finely cubed, cold
2 large yolks
2 tsp dijon mustard
2 T finely chopped onion
2 T finely chopped parsley
3-4 tsp avocado or other neutral oil
4 dashes Worcestershire sauce
A few anchovy filets (optional)
Pinch of crushed chilies (optional)
Mix everything but beef and yolks. Pour over beef, toss on yolks, and lightly combine with fork. Don’t overwork it, you want the beef to retain some texture. Salt and pepper to taste.
