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 ↓
Roast Duck
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 400°F (200°C).
Rub the duck inside and out with coarse sea salt and black pepper.
In a bowl, combine bread crumbs, melted butter, hot water, chopped giblets, and season with salt and pepper.
Fill the duck with the breadcrumb mixture.
Roast
Place the duck in a baking pan and pour boiling water over it.
Roast the duck for 1 to 2 hours, basting often.
Dredge the duck with flour toward the end of cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat, whose fat renders during roasting to keep the flesh moist and crisp the skin.
- Bread crumbs
- Absorb the butter and giblet juices in the stuffing, keeping the filling moist and lightly textured.
- Butter
- Adds fat and richness to the breadcrumb stuffing, helping it brown and taste savory.
- Flour
- Dredged over the duck near the end of cooking to help the skin brown and crisp.
The step that matters
Dredge the duck with flour toward the end of cooking. Flour browns faster than the skin when exposed to dry oven heat, so adding it too early can scorch or burn. Adding it late gives a golden, crisp surface.
