Why it works: Butter and bread 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 ↓
Baked or Shirred Eggs
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Butter an egg shirrer.
Cover the bottom and sides with fine cracker crumbs.
Break an egg into a cup.
Carefully slip it into the shirrer.
Cover the egg with seasoned bread crumbs.
Bake
Bake in a moderate oven at 350°F (175°C) until the white is firm and the crumbs are brown.
Make the tomato version
Cut a slice from the stem end of the tomato.
Scrape out the pulp.
Slip an egg into the tomato.
Sprinkle with salt and pepper.
Cover with buttered crumbs and bake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm, tender mass as the proteins cook in the heat.
- Butter
- Adds fat that helps the crumbs brown and gives a rich flavor.
- Fine cracker crumbs
- Form a crisp base that keeps the egg from sticking to the shirrer.
- Seasoned bread crumbs
- Create a golden, crisp topping through browning in the oven.
- Small tomatoes
- Hold the egg in a moist, slightly acidic shell while it bakes.
The step that matters
Bake until the white is firm. Egg white proteins set with heat, so the white needs to firm fully while the yolk stays soft. Removing the eggs once the white is set, and before the yolk turns chalky, keeps the texture tender. Watch the crumbs for browning at the same time.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (butter, egg, bread, pepper):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Tomatothe original
Fit is the average pairing score against butter, egg, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
