Balsamic Caramelized Onions

Vinegar is commonly used in banishing spells.

1/2 or whole onion cut into strips
1-2 tbsps olive oil
1-2 tbsp balsamic vinegar
1/2-1 tsp sugar
salt and pepper to taste

Heat oil in pan over medium-high. Add onions to pan and cook for a few minutes. Add vinegar to pan and cook for a few more minutes. Add sugar, salt, and pepper and stir to flavor onions. Reduce heat to medium-low and cook until dark in color but not burnt. Patience is a virtue.
