Thai style shrimp fry with half Caramelised onions

To caramelise onions :

Ingredients:

White onions 2 nos cut long and thin.

2 tbs brown sugar
1-2tsp balsamic vinegar

oil 1tsp

Method
Heat oil in a large frypan over low heat. Add the onions and a good pinch of
salt and cook very slowly for 15-20 minutes, stirring occasionally to prevent
them from catching. Don't be tempted to turn the heat up, as you don't want the
onions to burn.
