Why it works: Beef and potato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,052 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Remnant of Roast Beef
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Layer thin slices of beef in a deep dish and sprinkle with flour, pepper, and coarse sea salt.
Add a layer of raw potatoes, also sprinkled with flour, pepper, and coarse sea salt.
Cover with gravy or stock and scatter small pieces of butter on top.
Bake at 400°F (200°C) for 1.5 to 2 hours, covering with a plate for the last hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Protein that firms and browns as it cooks, giving the casserole its meaty flavor.
- Raw potatoes
- Starch that softens during baking and absorbs cooking liquid, adding body to the dish.
- Flour
- Starch that coats the beef and potatoes and helps thicken the juices into a sauce.
- Butter
- Fat that adds richness and helps the top brown in the oven.
- Gravy or stock
- Liquid that moistens the layers and carries heat through to cook the beef and potatoes.
The step that matters
Covering for the last hour. Covering with a plate traps steam around the layers, keeping the beef and potatoes moist and tender while the dish finishes cooking. Skipping the cover can leave the beef dry and the potatoes unevenly cooked.
