Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Orange Jelly
Ingredients
Directions
Make the jelly
Squeeze the juice from the oranges.
For every pint of juice, add 1 pound of sugar and ¼ ounce of dissolved isinglass.
Boil the mixture and skim until a jelly forms.
Test and cool
Take a spoonful out and drop a bit into a glass of cold water.
If it falls in a mass, the jelly is done.
Let it cool in the air for a few minutes.

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
- Juice of oranges
- Provides the liquid base and the orange flavour of the jelly.
- Sugar
- Adds sweetness and helps the jelly set firm and hold its shape.
- Isinglass
- Gelling agent that sets the liquid into a jelly as it cools.
The step that matters
Testing the set in cold water. The jelly only sets once it has boiled down enough to concentrate the sugar and gelling agent. Too little boiling leaves it runny, while over-boiling makes it stiff, so the cold-water test shows when it is ready.
