Ingredients
- 300 g beef tenderloin
- 2 large spoonfuls black truffle sauce
- 2 portions soba noodles
- 1 cucumber
- 1 red onion
- 4 cloves garlic
- 100 g shimeji mushrooms
- 2 chili peppers
- 1 soft-boiled egg
- 2 tbsp light soy sauce
- 1 tbsp oyster sauce
- 1 tsp black pepper
- to taste cooking oil
- to taste toasted sesame seeds
Instructions
- 1Cut the beef tenderloin

Take 300g of beef tenderloin and cut it into small cubes on a wooden cutting board using a knife. Hand-cut cubes provide a much better texture compared to using a food processor.
Tip: Avoid using a food processor so that the beef retains its chunky and satisfying texture. - 2Mince the garlic

Take individual garlic cloves and finely mince them on the wooden cutting board using a sharp cleaver. This provides an aromatic base for the beef sauce.
Tip: Mince the garlic finely to ensure the flavors disperse evenly throughout the oil when sautéing. - 3Chop the red onion

Take half of a red onion and chop it into small pieces on the wooden cutting board. Cutting red onion this way is fast and helps prevent tearing up.
Tip: Chop the onion finely so it softens quickly and blends smoothly into the sauce aromatics. - 4Chop the shimeji mushrooms

Take a cluster of shimeji mushrooms and chop them finely on the cutting board. Adding mushrooms enhances the overall umami flavor profile of the sauce.
Tip: Any type of mushroom can be used if shimeji is unavailable, but they should be chopped small to blend into the meat mixture. - 5Sauté garlic and onion

Heat oil in a pan, then add the minced garlic and chopped red onion. Sauté them together over heat until fragrant and the onions change color.
Tip: Ensure the oil is adequately heated before adding the aromatics to release their full fragrance without burning. - 6Cook the beef cubes

Add the freshly cut beef cubes into the pan with the sautéed garlic and onion. Stir-fry continuously until the beef is fully browned.
Tip: Stir frequently to ensure the beef cubes brown evenly alongside the aromatic base. - 7Add chopped mushrooms

Add the minced mushrooms into the pan with the browned beef cubes and continue stir-frying to enhance the umami flavor.
Tip: Shimeji mushrooms work great for this, but any variety of mushroom can be used.
