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 Pudding
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.
Prepare
Preheat the oven to 350°F (175°C).
Butter a pudding dish and cover the bottom with slices of bread.
Assemble
Layer the prepared rhubarb over the bread and sprinkle with brown sugar.
Add another layer of bread and repeat until the dish is filled.
Beat the eggs with some pulverized sugar and pour over the pudding.
Bake and serve
Cover the dish and bake until set, then remove the cover to brown.
Flavor with lemon or nutmeg before serving.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart fruit flavor and moist filling between the bread layers.
- Bread
- Soaks up the custard and forms the soft, structured body of the pudding.
- Eggs
- Bind the custard and set during baking to give the pudding its firm texture.
- Brown sugar
- Sweetens the rhubarb and adds caramel notes as it bakes.
The step that matters
Bake covered until set, then uncover to brown. Covering traps steam so the egg custard cooks through gently without drying out. Removing the cover lets surface sugars and proteins brown. Uncovering too early can dry the top, while leaving it covered leaves the top pale.
Swap the rhubarb
How well each one fits the dish's main ingredients (bread, sugar, egg, lemon):
- Nutmegfits better
- Cinnamonfits better
- Parsleyfits better
- Rhubarbthe original
Fit is the average pairing score against bread, sugar, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
