How to Make Sweet Sour Onion Relish

Heat 2 tablespoons of olive oil in a 1 1/2-quart saucepan over medium heat.
Add 4 cups sliced Vidalia onions and 2 tablespoons of granulated sugar.
Cover and cook, stirring occasionally, until onions are softened and have released most of their liquid (approximately 10-20 minutes).
Uncover and continue cooking, stirring frequently, until onions turn a deep golden brown color (another 10-20 minutes).
Add 2 cloves minced garlic, 1 teaspoon fresh rosemary, and 1/4 cup apple cider vinegar.
Cook and stir for 3 minutes, until fragrant.
Season generously with salt and freshly ground black pepper. Add more vinegar to taste if desired.
Let cool completely before storing in an airtight container in the refrigerator for up to 3 days. The flavor will deepen over time!
