Ingredients

Blue cheese and gherkin sauce
Method
Main
1.Heat a barbecue or char-grill pan to high heat. For pickled beet, place vinegars, sugar, spices and 100ml water in a saucepan over medium-high heat and bring to a simmer, stirring to dissolve sugar. Place beetroot and onion in a bowl, pour in hot pickling liquid, stir to separate the layers of beetroot, then place on a bowl of ice for 10 minutes to cool and lightly pickle.
2.Shape beef into 4 patties about 2cm-thick and grill, turning once, until cooked medium (about 3 minutes each side). Set aside on a warm plate to rest (2 minutes).
3.Meanwhile, for blue cheese and gherkin sauce, combine ingredients in a bowl and season to taste.
4.Toast bun halves cut-side down on grill (1 minute), then assemble burgers from the base with lettuce, tomato, beef patty, a good dollop of sauce and beetroot, and serve.
