A simple side dish of mashed sweet potatoes flavored with spicy yellow mustard and freshly squeezed lemon juice.


  • 1 lb sweet potatoes (about 3 large), peeled
  • 3 tablespoons butter
  • 2 tablespoons heavy cream
  • 1 to 2 tablespoons prepared English mustard (Colman's)
  • Juice of 1/2 lemon (1-1/2 tablespoons or more to taste)
  • Salt and freshly ground black pepper


  1. Peel the sweet potatoes and cut them into 1-inch cubes. Place in a saucepan, sprinkle with 1/2 teaspoon salt and cover with cold water. Bring to a boil and cook until tender when pierced with a knife, 12 to 15 minutes. Drain and return to the pan.
  2. Place the pan back on the heat and allow the water to evaporate, 1/2 to 1 minute. Transfer to a mixing bowl and add the butter, cream and mustard. Stir to combine and once the butter melts, mash all the ingredients together with a potato masher. Stir in the lemon juice, season to taste with salt and pepper and add more lemon juice and/or mustard if desired. Serve immediately.
