Why it works: Plum and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 2,313 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Damson Jelly
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Extract the juice
Bake the damsons and bullaces in a 300°F (150°C) oven or boil them in a water bath until soft.
Pour off the clear juice from the fruit.
Strain the juice.
Weigh the juice.
Make the jelly
Boil the juice quickly without sugar for 25 minutes.
Remove the juice from heat.
Stir in 10 ounces of sugar for each pound of juice.
Stir the jelly often before adding sugar and constantly afterwards.
Boil quickly for an additional 6 to 10 minutes.
Skim off any scum.

What each ingredient does
- Damsons
- Provide the fruit's pectin and tart flavour that set and season the jelly.
- Bullaces or pale plums
- Add extra pectin and body to help the jelly set.
- Sugar
- Adds sweetness and helps the jelly set and keep its texture.
The step that matters
Stirring in the sugar. Sugar must dissolve fully and be stirred in evenly before the final boil, or the jelly may crystallise or set unevenly. Stir often so it does not scorch on the base of the pan.
