Mindbogglingly easy, astoundingly good.
- Take a quantity of Balsamic Vinegar (I use 2 cups).
- Put in a saucepan over high heat until it just reaches a boil
- Reduce heat to simmer
- Reduce by 1/2, stirring occasionally
The result should be thickened, with very intense flavor. Excellent drizzled on salad, bread, ice cream, pizza. Will keep indefinitely in the fridge.
