Chef’s secrets

Try using store-bought beef cubes for your skewers. If necessary, cut the biggest cubes to get similarly sized 2 cm (¾ in.) cubes.

To prepare the pickled onions, finely slice one small red onion and place in an airtight bowl or container. In a small saucepan, bring 60 mL (¼ cup) of white vinegar, 60 mL (¼ cup) of water and 5 mL (1 tsp.) of sugar to a boil. Remove from heat, pour over onions and let sit for a few minutes.
