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
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook the rhubarb
Combine rhubarb, sugar, and water in a saucepan.
Cook over medium heat until the rhubarb is soft.
Finish the sauce
Cover rhubarb with boiling water.
Let stand for 5 minutes, then drain.
Cook until desired consistency.
Alternative baked method
Alternatively, bake rhubarb in an earthen pudding dish at 300°F (150°C) for a long time for a rich red color.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Rhubarb
- Provides the main body and tart flavor, and softens into the sauce as it cooks.
- Sugar
- Adds sweetness that balances the rhubarb's tartness and helps it break down.
The step that matters
Cook until desired consistency. Rhubarb keeps thickening as its cell walls break down and water evaporates. Stopping too early leaves a thin sauce, while cooking too long turns it stiff and dull.
