Orange Marmalade

Ingredients

three pounds of sweet oranges
half pints
two pounds of lemons

Directions

Prepare the fruit

Take three pounds of sweet oranges and two pounds of lemons, with the same weight of sugar.
Pare the fruit thinly and cut it into fine chips.
Boil the chips until quite tender.
Scrape off the pulp from the inner skins and pick out the seeds.
Place a dish with a little water, and put skins and seeds in it to extract all the juice possible.

Make the marmalade

Strain the water from the chips and skins, and use one and a half pints for the syrup.
Boil the pulp, chips, etc., for twenty minutes.
Cover the mixture when it is cold.

What each ingredient does

Sweet oranges: Provide the main bitter-sweet flavour and the pectin-rich peel that lets the marmalade set.
Lemons: Add acidity and extra pectin, helping the marmalade set and balancing the sweetness.
Sugar (in the method): Sweetens the marmalade and, when boiled, helps it thicken and set.
