Alhough it takes some time on the stove, it's dead easy to make and a layer of onion-thyme jam could add depth of flavor to all kinds of dishes, from pizzas to tarts and sandwiches. Feel free to try other herbs, too, such as rosemary or sage.
2 tablespoons unsalted butter
2 tablespoons olive oil
4 medium sweet onions, chopped (about 4 cups)
2 tablespoons fresh thyme leaves (or 1 1/2 teaspoons dried)
1 bay leaf
1 roasted garlic clove, mashed (optional)
Freshly ground black pepper
1/4 cup apple cider vinegar
2 tablespoons brown sugar
Melt the butter and olive oil in a heavy-bottomed pot. Add the onions, thyme, bay leaf, garlic, 1 teaspoon salt, and a few cracks of pepper. Cover and cook over medium-low heat for 20 minutes.
Add the vinegar and sugar and cook, stirring frequently, 20 minutes or longer until thickened. Remove bay leaf.
Transfer jam to a bowl and let cool. Season with additional salt and pepper, if desired.
Can be refrigerated for a few days; return to room temperature before serving.
