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 ↓
Boast 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.
Season and roast the beef
Rub the top and sides of the beef with coarse sea salt and black pepper.
Place a few small pieces of butter on top of the beef.
Put the beef in a dripping pan.
Pour about 2 tablespoons of hot water into the pan.
Place the pan in a 400°F (200°C) oven.
Baste the beef frequently while it cooks.
If the top burns, open the oven door slightly.
When cooked, place the beef on a hot platter.
Make the gravy
Sprinkle flour in the dripping pan.
Stir constantly.
Add enough boiling water to make the gravy the right thickness.
Strain the gravy.
Serve the gravy in a separate dish.
Prepare and roast the potatoes
Peel medium-sized potatoes.
Cut the potatoes in half lengthwise.
Place the potatoes around the beef in the pan about 30-45 minutes before serving.
Turn the potatoes frequently.
Baste the potatoes frequently.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef roast
- Forms the main body of the dish, cooking through in the oven to a tender, juicy centre.
- Butter
- Adds fat that enriches the meat and helps the surface brown as it roasts.
- Flour
- Thickens the pan juices into gravy as it cooks and mixes with the drippings.
- Medium-sized potatoes
- Absorb roasting fat and juices from the pan, browning on the outside while softening inside.
The step that matters
If the top burns, open the oven door slightly.. Sugars and proteins on the surface brown quickly at high heat, so a burning top means the oven is running too hot for the surface. Briefly venting the door lowers the heat around the roast, letting the interior keep cooking without scorching the outside.
Swap the potato
