Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Savory Cheese Toast
Ingredients
Directions
Make the cheese sauce
Simmer vinegar, red pepper, bay leaf, onion, and celery for 10 minutes.
Strain the mixture into a scant pint of cream sauce.
Stir in a tiny pinch of baking soda to prevent curdling.
Add grated cheese and cook until melted.
Serve
Pour the cheese sauce over crisp circles of buttered toast.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts into the cream sauce to give it rich flavor and a smooth, thick body.
- Cream sauce
- Forms the creamy base that carries the cheese and coats the toast.
- Vinegar
- Adds a sharp acidity that brightens the flavor of the rich sauce.
- Onion
- Contributes savory aroma and flavor to the strained base.
- Baking soda
- Neutralizes acidity in the sauce so it is less likely to curdle.
The step that matters
Adding the cheese. Cheese cooked at too high a heat or for too long can turn stringy or greasy. Adding it to the warm sauce and cooking gently until just melted keeps the sauce smooth.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, pepper, onion, cream, sauce, cheese):
- Garlicfits better
- Tarragonfits about as well
- Celerythe original
- Capersfits about as well
Fit is the average pairing score against vinegar, pepper, onion, cream, sauce, cheese. Candidates are from the same food group and used in at least 100 recipes.
