  1. To prepare the oranges, quarter the oranges and slice them very thin. Remove and discard any seeds.
  2. Divide the sliced oranges evenly between two 1-pint wide-mouth jars. Press down fi rmly with a mallet or wooden spoon until the juice is released.
  3. To make the brine, combine the water, sugar, whey, and salt. Pour the brine over the oranges, dividing it evenly between the jars. Add orange juice or water if necessary to cover the oranges completely. The liquid should reach to about 1 inch below the top of the jars.
  4. Let the marmalade ferment at room temperature for 3 days.
  5. Store the marmalade in covered containers in the refrigerator for up to 2 months. Note: If the marmalade develops white spots on the surface, lift them off with a spoon and discard them. The marmalade is still safe to eat.

Makes two 1-pint jars
