Asian-Style Beef Skewers

Ingredients:

Beef

• 600 g sirloin steak, cut into 1 cm cubes.
• 2 tbsp. l. olive oil
• Fresh coriander leaves, for serving

Hot dipping sauce

• 1 cup mayonnaise
• Zest and juice of 1 lime
• 1 tbsp. l. rice vinegar
• 1.5 tsp. sesame oil

Preparation:

1. Beef:
   
   Heat olive oil in a cast-iron skillet over medium-high heat. Season the beef with 1 teaspoon salt and 1/2 teaspoon black pepper. Cook the beef (in batches if necessary, being careful not to overcrowd the pan) on all sides until medium-rare, 2-3 minutes.
2. Transfer to paper towels to drain excess oil and set aside to cool.
3. Meanwhile, prepare the dipping sauce.:
   
   In a bowl, combine mayonnaise, lime zest and juice, vinegar, sesame oil, sugar, red pepper flakes, and some salt and black pepper.
4. Thread the beef pieces onto toothpicks (2 pieces each). Sprinkle with cilantro and serve with the sauce.
