Why it works: Blackberry and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 1,033 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Blackberry Jelly
Ingredients
Directions
Cook the blackberries and strain through a bag to extract the juice.
In a pot, combine 1 quart of the juice with 1 pound of white sugar and stir until dissolved.
Bring the mixture to a boil and cook until it thickens into a jelly.

What each ingredient does
- Blackberry juice
- Provides the liquid base and the fruit flavor that sets the jelly's character.
- White sugar
- Sweetens the jelly and helps it thicken and set as it cooks.
The step that matters
Cooking until it thickens. Sugar and fruit pectin set into a gel only at a high enough concentration and temperature. Stopping too early leaves a runny syrup, while cooking too long can make the jelly stiff and dull.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
