Caramelized Onion, Rosemary & Mozzarella Crostini

Caramelized onions are a great way to add sweetness to lots of dishes. Use this technique for a number of other recipes including French Onion Soup or simply follow this “deconstructed” French onion crostini for a beautiful appetizer.
Prep Time:  10 minutes - Cook Time:  80 minutes - Total Time:  90 minutes
Yield: 6-8 servings
- 2 Tbsp Avocado Oil
- 3 Onions, cut into 1/2 rings or petals
- 1/2 tsp Sugar
- 1/4 cup Dry White Wine
- 1 crusty Italian Baguette
- 1/2 fresh Mozzarella cheese
  1. In a large sauté pan, heat the Avocado Oil over medium heat. Add the onions, Sel Gris, sugar, and Mediterranean Rub.
  2. Cook over medium-low heat, stirring occasionally, as the onions slowly caramelize and reduce, about 50-60 minutes.
  3. Turn the heat up to medium-high and add the wine to de-glaze the pan. Stir in the vinegar. Set aside.
  4. Preheat the oven to 400°F.
  5. Cut the baguette into ¼” slices and arrange on a baking sheet. Drizzle with Rosemary Olive Oil and bake until light brown in color, about 10 minutes.
  6. Top each of the baguette slices with mozzarella cheese, caramelized onions, and a pinch of Mediterranean Rub. Return to the oven until the cheese is melted and golden in color, about 10 minutes. Enjoy!

I made this recipe and it was delicious. However, as I read the recipe I was confused. In the list of ingredients it called for Chianti Wine Vinegar. In the directions that was not mentioned but rather Sherry Vinegar. Error or interchangeable?
