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 ↓
Prepared Bread Crumbs
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.
Make the crumbs
Break stale bread into small bits and place them on a baking pan.
Bake in a 350°F (175°C) oven, watching closely to prevent scorching.
Once hot and crisp, crush the bread and sift it.
Use fine crumbs for breading and coarse crumbs for puddings or pancakes.
Make the crackers
For crackers, sift flour and baking powder into a bowl.
Add melted butter, salt, beaten egg white, and milk; mix to form a stiff dough.
Knead the dough well, then roll it out thin like pie crust.
Cut into rounds or squares and bake until light brown.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Dried and crushed into crumbs that give breading and puddings their body.
- Flour
- Provides the structure that holds the cracker dough together.
- Baking powder
- Releases gas during baking so the crackers rise and lighten.
- Butter
- Adds fat that tenderizes the dough and promotes light browning.
- Egg white
- Binds the dough and helps it set firm during baking.
- Milk
- Adds moisture that hydrates the flour into a workable dough.
The step that matters
Watching the crumbs in the oven. Bread dries and browns quickly at the end, so it can scorch before it is fully crisp. Scorched crumbs taste bitter, and under-dried ones stay soft and go stale fast.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
