Heat sesame seeds in a pan over medium heat until golden and aromatic—takes around 2–3 minutes. Let them cool, then grind them using a mortar or smush them in a sealed bag with a rolling pin.

Trim the beef roast and cut it into slices about 2 x 3 inches and 1 cm thick. Be sure to slice against the grain. Put the pieces into a big bowl.

In another bowl, mix together the sesame seeds, brown sugar, soy sauce, garlic, sesame oil, hoisin sauce, mirin, and pineapple juice if using. Pour the marinade over the sliced beef, mix it up well, cover the bowl, and chill in the fridge for an hour.

Place skewers on a grill preheated to medium-high (around 400°F). Cook each side for 3–4 minutes until the beef is done and a little caramelized at the edges. Serve hot as a starter or main dish.
