How to Cook Sweet Caramelised Onion

I have been meaning to put this recipe on the website for a little while. Every time I serve these delicious sweet caramelised onion, I always get asked how I made them. It is a very simple dish once you know how!

The addition of sugar and brandy really makes a huge difference in the depth of flavour. If you don’t have brandy don’t worry, I have used bourbon before and that was fantastic also.

I like to have a jar of caramelised onion in the fridge ready for emergency use. The onions give all sorts of dishes a lift. Take a look at this Wagyu Bruschetta with Caramelised Onion and Brie we were served at a Degustation dinner!

Even the traditional bangers and mash (Sausages & Mashed Potato) is made better with my sweet caramelised onions.

Without further ado, I give you my step by step recipe for Sweet Caramelised Onion.
