- Heat the butter in a large pan over low heat. Add the sliced red onions and cook them slowly, stirring regularly, until they are deep golden brown and soft (allow at least 25 minutes – patience is the secret!).
- Then add the caramel syrup and balsamic. Let everything simmer gently for about 5 more minutes so the flavors can really blend.
