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 ↓
Marrow Toast
6 slices of toastIngredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the marrow
Soak the marrow in tepid water for about 2 hours.
Cut the marrow into 1-inch lengths and place them in cold water.
Bring the water to a boil, then drain the marrow well.
Assemble and bake
Prepare 6 slices of very hot, well-buttered toast.
Place the marrow on the toast, breaking it up and spreading it with a fork.
Season with salt and pepper.
Place the toast in a hot oven (400°F / 200°C) until the marrow is thoroughly melted.
Serve
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Marrow
- Melts into the toast, giving it a rich, fatty, savoury body.
- Butter
- Adds fat and moisture to the toast and helps the marrow spread.
The step that matters
Draining the marrow well after boiling. Excess water left on the marrow dilutes its fat and makes the toast soggy, so it should be drained thoroughly before it is placed on the toast.
