my go-to dressing for all sorts of uses
Place olive oil and garlic slices in pan over low heat and let simmer for ~ 8 min. Be careful not to burn the garlic, adjusting heat as needed.
Remove garlic slices from oil and add balsamic vinegar and red wine vinegar and let simmer for ~5 min. It should somewhat thicken and reduce. You may need to adjust the heat slightly higher.
Remove from heat and add the brown sugar, salt and pepper. Using a whisk, blend together and let cool in pan for ~ 15 min.
Transfer to a glass container for easy storage and pouring.
