The light acidity of balsamic vinegar perfectly balances the sweet and smoky profile. fresh garlic imparts a savory pungency that deepens complexity without overwhelming. Keep salt and pepper simple to enhance, not mask, the vibrant flavors. This seasoning mix is a foundation you can tweak-try cumin or chili flakes for a southwestern twist,or thyme for a Mediterranean flair.
