Step 1

Trim all excess fat chunks off the steaks. Then finely chop the filets into ¼ inch pieces. Do this by cutting the steaks into fine strips. Cut the strips in halves or thirds. Then cut the steak ribbons crosswise.

Step 2

Mince the shallots and capers. Zest and juice the lemon. In a measuring cup, add the egg yolk, 1 tablespoon lemon juice, and spicy mustard. Stir to combine.

Step 3

Set out a mixing bowl. Add the chopped steak, minced shallots, capers, egg yolk mixture, parsley, olive oil, lemon zest, 1 teaspoon salt, and ½ teaspoon cracked black pepper. Mix well.

Step 4

Taste, then add additional salt, pepper, or lemon juice if desired.

Step 5

Serve immediately. For traditional plating, press the steak tartare into ramekins, then flip it out onto small serving plates in the shape of a disk. Garnish with extra parsley and/or capers. You can also rest an extra egg yolk on top, but be aware this will make the tartare texture extra dense and silky.
