Step 1: Cut the onion in half length ways and peel. Using a very sharp knife, slice your onion very finely into slices along the grain.
Step 2: Place the sliced onion in a bowl and, with your hands, massage in the salt and sugar, cover the bowl with glad wrap and set aside for at least two hours.
Step 3: After 2 hours you will see that the onion slices have collapsed a little and released some liquid. Using clean hands again, squeeze the sliced onions to get out the last of their juices and place in another bowl, and add in the vinegar.
Step 4: Onions can be used straight away, although I recommend leaving in the fridge for a few hours, they will keep in the fridge for about 4 - 5 days.
