Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rhubarb
Provides the tart flavour and softens into the body of the stew as it cooks.
Apples
Add sweetness and body, breaking down to thicken the stew slightly.
Lemon
Adds acidity and brightness that balances the sweetness.
Sugar
Adds sweetness and balances the sharp tartness of the rhubarb and lemon.

The step that matters

Stew until tender. Rhubarb softens and breaks down with gentle, sustained heat. Stopping too early leaves the pieces fibrous and firm, while over-boiling turns them to mush and can make the fruit taste dull.
