1 Tablespoon Butter

1 Tablespoon Olive Oil

2 x Medium Red Onions (thinly sliced preferably with a mandolin)

1 x Tablespoon Soft Brown Sugar

1 Tablespoon Balsamic Vinegar

1 Tablespoon Soy Sauce

  • Heat 1tbsp of the oil and 1tbsp of the butter in a heavy bottomed frying pan (we use the 20cm Le Creuset),

  • Add the onions. Cover with a lid and cook gently for about 15 minutes, stirring occasionally.

  • Uncover the pan, increase the heat slightly and sprinkle in the sugar. Cook, stirring frequently, until the onions begin to caramelize and brown.

  • Add the balsamic vinegar and soy sauce and cook briskly until the liquid evaporates.

  • Season and leave your caramelised onions to cool slowly.
