Orange Marmalade— No. I
Ingredients
Directions
Prepare the peel
Pare the rind of the oranges as thin as possible and cut it into small pieces.
Tie the rind in muslin and boil slowly until clear.
Peel off the white inner rind and break the oranges into pieces.
Cook and strain
Cover the orange pieces with water and boil for 45 minutes.
Strain the mixture through a flannel bag.
Add half of the boiled skins and boil for 20 minutes, skimming off any scum.
Jar
Pour into jars and cover with the remaining skins when cool.

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
- Oranges
- Supply the peel, pulp and juice that give marmalade its bitter flavour and pectin-rich body.
- Sugar
- Sweetens the marmalade and, as it concentrates, helps it set into a spreadable gel.
The step that matters
Boiling the rind until clear. Thin, slow boiling softens the peel so it becomes tender and translucent. Rushing it leaves tough, opaque pieces, and the peel is what gives marmalade its texture.
