Ingredients

  • 1 -1/2 lbs. sweet potatoes, peeled and cut into 1-inch cubes
  • 4 small garlic cloves, sliced thin
  • 3 cups low-sodium chicken or vegetable broth
  • 3 Tbs. chopped fresh thyme or 1-1/2 tsp. dried thyme
  • 2 Tbs. unsalted butter
  • kosher salt
  • freshly ground white pepper
  • 2 Tbs. aged balsamic vinegar or balsamic vinegar reduction

Method

  • Place sweet potato cubes and garlic in a saucepan and pour in chicken or vegetable broth to within a half inch of the top of the potatoes.
  • Boil until very soft (the potatoes will sink down into the liquid as they cook), 12-15 minutes.
  • Drain, reserving cooking liquid.
  • Return potatoes to saucepan and mash with potato masher.
  • Slowly add some of the cooking liquid, stirring until you get the consistency of a loose puree.
  • It need not be perfectly smooth.
  • Stir in thyme and butter, adding more to taste if needed, and season with salt and white pepper to taste.
  • Keep warm in a double boiler.
  • Drizzle aged balsamic vinegar over each portion just before serving.
