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 ↓
Rhubarb Sauce
Ingredients
Directions
Prepare
Wash and peel the rhubarb, then cut it into 1-inch pieces.
Sprinkle the rhubarb generously with sugar, using 1 cup of sugar for every 3 cups of rhubarb.
Shake well to combine and let it stand until the sugar is moist with juice.
Cook
Heat slowly on the back of the range until the rhubarb is tender, without stirring.
If the mixture is too watery, uncover it during the latter part of cooking.

What each ingredient does
- Rhubarb
- Provides the tart flavor and breaks down into the sauce's body as it cooks.
- Sugar
- Sweetens the rhubarb and draws out its juice, forming a syrup that softens the fruit.
The step that matters
Heating slowly without stirring. Gentle, slow heat lets the rhubarb soften and release juice evenly without scorching on the bottom. Stirring would break the pieces down unevenly, so the sauce can turn mushy and cloudy instead of holding a clean texture.
