Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Egg Toast
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 toast
Cut rounds of stale bread and toast them.
Moisten the toast slightly with a mixture of butter and water.
Lightly sprinkle with paprika and dust with celery salt.
Make the topping
Chop the whites of the hard-boiled eggs very fine.
Mix the chopped egg whites with the drawn butter.
Spread the mixture on the toast and season with salt, pepper, and parsley.
Rub the yolks through a colander to create a yellow powder and cover the sauce.
Bake and serve
Place in a hot oven at 400°F (200°C) for three minutes and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Forms the toasted base that holds the egg topping.
- Butter
- Adds richness and moisture, keeping the toast from drying out.
- Hard-boiled eggs
- Provide the main savory body of the topping, with whites chopped and yolks sieved.
- Drawn butter
- Binds the chopped egg whites and adds fat for a smooth, rich spread.
The step that matters
Place in a hot oven at 400°F (200°C) for three minutes and serve.. Only a brief time in a hot oven is needed to warm the topping and toast without drying or overcooking the egg and butter. Leaving it too long can dry the topping and scorch the paprika.
Swap the celery
How well each one fits the dish's main ingredients (bread, butter, egg, pepper, parsley):
- Thymefits better
- Nutmegfits better
- Marjoramfits better
- Celerythe original
Fit is the average pairing score against bread, butter, egg, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
