Ingredients

  • 1 1/2 pounds leeks, sliced
  • 1 onion, chopped
  • 1 potato, cubed
  • 1 carrot, chopped
  • 1 tablespoon margarine
  • 1 tablespoon olive oil
  • 1 1/4 teaspoons prepared mustard
  • 2 teaspoons corn flour

Instructions

  1. In a large pot over medium heat, sauté the leeks, onion, potato and carrot in the butter or margarine and the olive oil for 10 minutes, or until all vegetables are tender.
  2. Mix the mustard powder and corn flour with the 1/2 cup water to make a thin paste. Set aside.
  3. Season the vegetable mixture with salt and pepper and sugar. Stir in the mustard-water mixture and the 5 cups water. Bring mixture to a boil. Stir in the bouillon cube, reduce heat and simmer for about one hour, until reduced by half.
