Currant and sugar barely smell alike, yet cooks put them together in 12,256 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Berries, currants, or cherries
- Supplies the juice and tart fruit flavor that cooks down into a thick, dark spread.
- Sugar
- Sweetens the fruit and helps the mixture thicken and turn glossy as it reduces.
The step that matters
Reducing the mixture by one fourth. As water evaporates, the fruit and sugar concentrate and thicken. Stopping too early leaves it runny, while cooking too long can scorch the sugar and make the spread overly stiff.
