Why it works: Rhubarb and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 1,852 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

What each ingredient does
- Rhubarb
- Breaks down into the bulk of the butter, providing its tart flavour and body.
- Sugar
- Sweetens the butter and helps it thicken as the mixture cooks down.
The step that matters
Simmer gently until thickened. Simmering slowly lets the rhubarb soften and release its juices while water evaporates, which concentrates the mixture into a spreadable butter. Too much heat can scorch the sugar on the bottom of the pot, so stir occasionally.
