Why it works: Rhubarb and lemon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 546 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Rhubarb Cheesecake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Stew the rhubarb until soft, then beat it well with a fork and drain all the liquid away.
Add the lemon juice, lemon rind, and sugar to the rhubarb.
Mix in the beaten eggs until well combined.
Bake
Pour the mixture into a prepared pie crust.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the main tart flavour and the bulk of the filling.
- Eggs
- Set as they bake, binding the filling into a sliceable custard.
- Lemons
- Add acidity and bright citrus aroma from the juice and rind.
- Sugar
- Sweetens the filling and balances the sourness of the rhubarb.
- Prepared pie crust
- Holds the filling in shape while it bakes.
The step that matters
Drain all the liquid away from the rhubarb. Excess liquid from the stewed rhubarb thins the egg mixture and can keep it from setting firmly. Removing it helps the filling bake into a sliceable texture rather than a runny one.
Swap the rhubarb
How well each one fits the dish's main ingredients (lemon, sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Rhubarbthe original
Fit is the average pairing score against lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
