To Make Orange Marmalade
Ingredients
Directions
Prepare the fruit
Choose the largest Seville oranges with clear skins.
Weigh the oranges and an equal amount of loaf sugar.
Cook the skins
Quarter the orange skins and place them in a pot.
Cover with water and bring to a boil.
Divide the oranges into segments and scrape out the pulp, removing all seeds.
Prepare a basin with cold water to discard the seeds and skins.
Once the skins are tender, strain them and scrape off the pith.
Make the marmalade
Cut the skins into thin slices about 1 inch long.
Clarify the sugar, then add the skins and pulp to it.
Stir well and boil for about 30 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: beta-damascenone (apple, rose).
Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Seville oranges
- Provide the pectin for setting, plus the bitter peel that gives marmalade its character.
- Loaf sugar
- Sweetens the marmalade and helps it set into a firm, spreadable gel with the fruit's pectin.
The step that matters
Soften the skins before adding the sugar. Sugar hardens and slows the softening of citrus peel. Cooking the skins until tender first keeps them from staying tough in the finished marmalade.
