Step 1

Pour 1 cup balsamic vinegar into a saucepan and add 1/2 Tbsp honey (if using).

Step 2

Bring to a low boil, then reduce heat to keep at a simmer for 12-15 minutes.* Stir occasionally until reduced by half and lightly coats the back of a spoon. It will thicken more as it cools. Transfer to a mason jar or air-tight container, let cool to room temperature then refrigerate for 3 to 4 weeks.
