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 ↓
Flank Steak
Ingredients
Directions
Prepare the steak
Score the flank steak on both sides.
Season it well with coarse sea salt and black pepper, then dredge it with flour.
Assemble the pan
Place the steak in a baking pan and add enough water to cover it.
Peel the potatoes and add them to the pan with the steak.
Make a dressing of bread crumbs, plenty of butter, and more salt and pepper.
Spread the dressing over and around the steak.
Bake
Bake the steak, basting it often.

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
- Flank steak
- Forms the main meat, which becomes tender with scoring and slow, moist baking.
- Flour
- Dredging coats the steak surface, helping it brown and thickening the pan liquid.
- Potatoes
- Absorb the savoury juices from the pan and soften as they bake.
- Bread crumbs
- Form a crisp, browned topping over the steak once baked.
- Butter
- Adds fat that enriches the dressing and promotes browning on the surface.
The step that matters
Basting the steak often. Regular basting keeps the surface moist with pan liquid and helps the dressing and meat brown evenly, preventing dryness during the long bake.
Swap the potato
How well each one fits the dish's main ingredients (pepper, flour, bread, butter):
- Shallotfits better
- Capsicumfits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against pepper, flour, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
