Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Scalloped Rhubarb
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Butter a pudding dish.
Layer and bake
Layer the ingredients in four parts, starting with rhubarb and finishing with bread crumbs.
Sprinkle sugar and grated lemon peel over the rhubarb.
Cut the butter into tiny bits and distribute over the bread crumbs.
Dredge the top with sugar.
Bake for 45 minutes and serve hot with cream or hard sauce.

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.

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 base that gives the dish its main flavour and moisture.
- Stale bread
- Soaks up the rhubarb juices and bakes into a soft, pudding-like layer.
- Granulated sugar
- Sweetens the tart rhubarb and helps the top brown lightly in the oven.
- Butter
- Adds richness and helps the bread crumbs brown as they bake.
The step that matters
Layering the ingredients. Rhubarb releases a lot of liquid as it cooks. Keeping the layers even and finishing with bread crumbs lets the crumbs absorb that juice, so the dish sets rather than turning soggy.
Swap the rhubarb
How well each one fits the dish's main ingredients (bread, sugar, butter, lemon):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Rhubarbthe original
Fit is the average pairing score against bread, sugar, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
