2.5 tbs

Preheat the oven to 240°C/220°C fan-forced. Peel the kumara and cut into fries. Place the fries on a lined oven tray. Drizzle generously with olive oil, season with salt and toss to coat. Add a dash of water to the tray and bake until tender, 20-25 minutes.
TIP: Leave the kumara unpeeled if you prefer!
While the fries are baking, combine the beef mince, fine breadcrumbs (see ingredients), egg and Aussie spice blend in a large bowl, then season with pepper. Shape the beef mixture into evenly sized patties slightly larger than the burger buns. You should get 1 patty per person. Transfer to a plate.
Thinly slice the brown onion. Scrub and grate the beetroot. In a large frying pan, heat a drizzle of olive oil over a medium-high heat. Cook the onion and beetroot, stirring, until softened, 5-6 minutes. Add the balsamic vinegar, brown sugar and the water and cook until dark and sticky, 4-5 minutes. Transfer to a bowl and cover to keep warm.
TIP: Wear rubber gloves to prevent the beetroot from staining your hands.
Wipe out the pan and return to a medium-high heat with a drizzle of olive oil. Cook the beef patties until just cooked through, 4-5 minutes each side. In the last 2-3 minutes of cook time, sprinkle the shredded Cheddar cheese over the patties and cover with a lid (or foil) to melt.
While the patties are cooking, bake the butter burger buns directly on a wire oven rack until heated through, 3 minutes.
Slice the burger buns in half, then spread with the Italian truffle mayonnaise. Top with the mixed salad leaves, a beef patty and some beetroot relish. Serve with the kumara fries.
TIP: If you're not a fan of truffle, dilute the flavour with some plain mayonnaise!
