8 oz. balsamic vinegar
1 onion (medium size onion and chop size)
1 shallot minced
4 cloves of garlic minced
Sauté onion, shallots and garlic in a little olive oil. Add the vinegar and bring to a boil. Reduce to a simmer and cook for 15 minutes. Strain the boil to separate sauce from solids. Return sauce to pan and continue simmering until it becomes slightly syrup like. Taste it and check the acidity. If it is too sharp add a tsp. of sugar a little at a time tasting as you go until you achieve a pleasant balance of flavor but don’t make it too sweet.
