If you want to get even more adventurous with your topping, try making a blueberry balsamic glaze. Combine blueberries and sugar in a saucepan, simmer them down, and then add balsamic vinegar.

Place the steak on the platter. Top with blueberry truffle sauce, drizzle with balsamic reduction, and garnish with sesame seeds and spring onion. Enjoy!
