Ingredients
  • 4 tablespoons butter
  • 3 Spanish (or yellow) onions, finely diced
  • 2 rosemary sprigs
  • 3 thyme sprigs
  • 1 cup granulated sugar
  • ¾ cup white balsamic vinegar
  • ⅛ teaspoon salt
Directions
  1. Melt the butter in a large, heavy-bottomed pot or skillet over medium-low heat.
  2. Add the diced onions and begin to caramelize, stirring occasionally, until soft and lightly golden, about 20 minutes. The onions should be about halfway to caramelized by this point.
  3. Tie the rosemary and thyme together with kitchen twine and add to the onion mixture.
  4. Add the sugar and let dissolve into the onions without stirring, about 5 minutes.
  5. Increase the heat to medium-high and cook until darkened in color and thick, about 5-10 minutes. Avoid stirring unless the mixture starts to burn.
  6. Reduce the heat to low and add the white balsamic vinegar, stirring until thick, about 5-10 minutes.
  7. Remove from the heat, remove the herb bundle, and stir in the salt. Let the onion jam cool completely, then store or serve as desired.
