Japanese Beef Tataki - cooking recipe

Ingredients

Beef and Garlic Chips
1 1/4 lbs center-cut beef tenderloin, trimmed
olive oil, for frying
salt & freshly ground black pepper, to taste
4 garlic cloves, thinly sliced lengthwise
Onion Ponzu
1/2 cup white onion, minced
3 tablespoons grapeseed oil
1 tablespoon fresh lemon juice
1 tablespoon unseasoned rice vinegar
1 tablespoon dark soy sauce
1/4 teaspoon fresh ginger, minced
1/4 teaspoon garlic, minced
Tataki Dressing
5 tablespoons soy sauce
1/2 cup unseasoned rice vinegar
1/8 teaspoon bonito flakes (optional)
3 whole scallions, thinly sliced on the diagonal (garnish)
2 tablespoons chives, thinly sliced (garnish)

Preparation

Heat a griddle over high heat, or preheat a gas grill to high. Lightly brush the beef with oil and season with salt and pepper. Prepare an ice bath.
Sear the beef on the griddle or grill on all sides until browned, about 2 minutes per side. Plunge into the ice bath and allow to cool, 3 to 4 minutes.
Remove the filet and drain well on paper towels, patting the meat dry.
In a 2-quart saucepan, heat 3/4 inch of oil over medium-high heat until shimmering hot. Add the garlic and fry until golden and crispy, about 1 minute. Remove with a slotted spoon. Drain on paper towel.
In a small bowl, whisk together the onion, oil, lemon juice, vinegar, soy sauce, ginger, and garlic until combined.
In another small bowl, whisk the soy sauce, vinegar, and bonito flakes, if using.
With a sharp carving knife, thinly slice the beef and arrange on 10 dinner plates. Spoon some of the onion ponzu on top of the beef, then drizzle on some tataki dressing, and top with the garlic chips, scallions, and chives.
