Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Roast Beef
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the beef
Preheat the oven to 400°F (200°C).
Dredge the beef lightly with flour and season with salt and pepper.
Place the beef in the oven and baste frequently while roasting.
Roast for 15 minutes per pound for rare, longer for well done.
Make the sauce
For the sauce, mix the drippings with Worcestershire sauce and tomato ketchup, then thicken with browned flour.
Make the Yorkshire pudding
For Yorkshire pudding, mix milk, beaten egg yolks, flour, and salt until smooth.
Beat the egg whites until stiff and fold into the batter.
Place the beef on a grating over a dripping pan and pour the pudding batter into the pan 45 minutes before the beef is done.
Drain excess fat if necessary, leaving enough to prevent sticking.
Cut the pudding into squares and serve around the beef.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites beaten stiff add lift and airy structure to the Yorkshire pudding batter.
- Flour
- Forms the batter's structure and, browned, thickens the sauce.
- Milk
- Adds moisture and richness to the batter, helping it set in the hot oven.
- Worcestershire sauce
- Adds savory, tangy depth to the pan drippings sauce.
The step that matters
Pour the batter 45 minutes before the beef is done. The batter needs a very hot oven and hot fat to puff and set. Adding it too early lets it cook too long and collapse, while adding it too late leaves it underbaked and dense.
Swap the tomato
How well each one fits the dish's main ingredients (beef, flour, pepper, sauce, ketchup, milk, egg):
- Capsicumfits better
- Shallotfits about as well
- Horseradishfits about as well
- Tomatothe original
Fit is the average pairing score against beef, flour, pepper, sauce, ketchup, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
