Step 1

Place the beef in the freezer for 30-40 minutes to firm up which will make it easier to slice. Add the garlic, apple, sugar, soy sauce, sesame oil, ginger and ground black pepper to a food processor and blitz until smooth.

Step 2

Slice the beef into wafer thin strips, across the grain and put in a bowl with the onion and spring onion. Add the marinade and mix – this is best done by hand to make sure the sauce is fully mixed into the beef.

Step 3

Oil a cast iron griddle pan with the vegetable oil using a pastry brush and place over a high heat. When hot, spread the beef and onions evenly over the top of the griddle using a pair of tongs, and cook for 2-3 minutes on each side until cooked through and the beef starts to caramelise.

Step 4

Serve immediately with freshly steamed rice and lettuce leaves to wrap, garnishing with sesame seeds and sliced spring onions.
