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 ↓
Stewed Rhubarb Au Croutons
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
Prepare the rhubarb by cutting it into pieces and placing it in a dish.
Add grated lemon peel and sugar to taste.
Assemble and bake
Cover the rhubarb with slices of bread.
Dot the bread with small pieces of butter.
Bake at 350°F (175°C) until the fruit is cooked and the bread is golden brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 cooks down into a soft stewed layer.
- Sugar
- Adds sweetness to balance the tartness of the rhubarb.
- Bread
- Forms a topping that browns and crisps in the oven as croutons.
- Butter
- Adds fat that helps the bread brown and gives it a rich flavor.
