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 ↓
Asparagus
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Wash the asparagus and cut off the roots.
Toast the bread slices and butter them.
Assemble and bake
Place the toast in a dish and arrange the asparagus on top.
Add a small piece of butter on the asparagus and sprinkle with salt.
Cover and cook for 2 hours at 300°F (150°C).
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
- Asparagus
- Main vegetable; softens during the long, covered cooking and gives the dish its flavor.
- Bread
- Forms the base that holds the asparagus and soaks up the cooking juices.
- Butter
- Adds fat for richness and moisture, and helps the toast brown.
The step that matters
Cover and cook for 2 hours. Covering the dish traps steam so the asparagus softens evenly. During such a long cook, the asparagus can turn mushy and the bread soggy if the cover does not fit well or the timing drifts.
Swap the asparagus
How well each one fits the dish's main ingredients (bread, butter):
- Leekfits about as well
- Potatofits about as well
- Tomatofits about as well
- Asparagusthe original
Fit is the average pairing score against bread, butter. Candidates are from the same food group and used in at least 100 recipes.
