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 ↓

Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make a dressing by mixing bread crumbs, pepper, salt, and chopped onions.
Place the dressing in the center of the steak, roll it up, and sew it together.
Bake
Place the rolled steak in a dripping pan and add pieces of butter on top.
Lay thin slices of salt pork or bacon on top of the meat.
Bake until brown, basting often.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the outer wrap and cooks into tender meat that surrounds the dressing.
- Bread crumbs
- Absorb moisture and give the dressing a soft, bready body.
- Onions
- Add savory flavor and aroma to the dressing as they cook.
- Salt pork or bacon
- Adds fat that bastes the meat and encourages browning and savory flavor.
- Butter
- Adds fat that promotes browning and a rich flavor on the surface.
The step that matters
Basting the steak while it bakes. Regular basting keeps the surface moist and carries fat and browned juices over the meat, which promotes even browning and prevents the lean steak from drying out during the long bake.
