Why it works: Cheese and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,130 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Celery Au Gratin
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the celery
Boil the celery in a small amount of salted water until tender, allowing it to cook almost dry.
Assemble the dish
Butter a baking dish and layer the celery, then add a layer of white sauce, alternating until all ingredients are used.
Cover the top with cheese and bread crumbs.
Bake
Bake in a hot oven at 400°F (200°C) until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main vegetable texture and mild flavor, softened by boiling until tender.
- Cheese
- Melts and browns on top, adding richness and savory flavor.
- White sauce
- Adds moisture and binds the layers together so the dish stays creamy.
- Bread crumbs
- Forms a crisp, golden crust on top through browning.
The step that matters
Cooking the celery almost dry. Celery releases water as it cooks. Leaving excess liquid in the dish would thin the white sauce and make the gratin soggy instead of creamy and set.
Swap the celery
How well each one fits the dish's main ingredients (cheese, sauce, bread):
- Capersfits better
- Garlicfits about as well
- Nutmegfits about as well
- Celerythe original
Fit is the average pairing score against cheese, sauce, bread. Candidates are from the same food group and used in at least 100 recipes.
