  3. Prep patties. In a bowl, combine beef, thyme, egg and 1/2 tsp salt together and mix well using clean hands. Divide mixture into 3 and shape into 1cm thick patties.

  5. Prep tomato & lettuce, warm buns & assemble. When frittes have 5 minutes cook time remaining, warm buns in oven on rack below kumara, for about 3 minutes. Once buns have toasted, spoon tomato sauce onto base of buns. Top with a beef patty, tomato, lettuce and quickled onions. Dollop over truffle Béarnaise and place a brioche lid on top.
