Caramelised Onions

Peel the onions and slice them in half vertically. Thinly slice each half with a sharp knife.

Put the extra virgin olive oil and butter in a large pan. Heat over medium-high heat, until the butter has completely melted.

Add the sliced onions, salt and pepper. Stir and cook until the onions have softened. It will take about 5-10 minutes.

It's time to add the sugar and water to caramelise the onions. Continue cooking for about 1 hour over moderate heat, continuing to turn so that they don't stick to the bottom.

The caramelised onions will be ready when they are soft and a nice golden colour. The liquid should have almost all evaporated.

Tip

For a stronger flavour you can add a teaspoon of Modena balsamic vinegar to the onions.
