The key to finely chopping filet mignon for this classic tartare is to chill it in the freezer before slicing and mincing it.
- 8 oz. trimmed center-cut beef tenderloin
- 3 tbsp. extra-virgin olive oil, plus more to taste
- 1 egg yolk
- 3 tbsp. salt-packed capers, soaked in water, rinsed, and drained
- 2 tbsp. minced ﬂat-leaf parsley
- 1 small red onion, minced
- 1 red thai chile, stemmed, seeded, and minced
- Fleur de sel and freshly ground black pepper, to taste
- Sherry vinegar, to taste
- Dijon mustard, for serving
Chill beef in freezer for 45 minutes. Transfer beef to cutting board and, using a very sharp knife, cut beef lengthwise into 1⁄8"-thick slices. Julienne each slice, and cut each julienne crosswise to ﬁnely mince beef. Transfer beef to a bowl and refrigerate.
Drizzle oil into a medium bowl and stir in egg yolk. Add capers, parsley, onions, and chiles; season with salt and pepper. Fold in reserved minced beef and season to taste with more of salt, pepper, and oil, if you like, along with a few drops of vinegar. Mound tartare on 2 chilled serving plates and serve with Dijon mustard.
Pairing note: The fresh, red-fruit nose and full, fat vanilla flavors of the Chateau du Chatelard Beaujolais Villages 2009 ($15) work well with this classic and vivacious dish —M.P.
