Why it works: Ketchup and sauce 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 ↓
Beef Scallop
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
In a stewpan, fry the chopped onion in beef dripping until brown.
Stir in the flour until smoothly mixed, then add vegetable stock and bring to a boil.
Season with salt, pepper, and tomato ketchup, then simmer for 10 minutes and strain into a basin.
Layer and bake
Butter a pie dish and layer cold beef slices, pouring some sauce over each layer.
Sprinkle with chopped parsley and strained onion, then continue layering with meat and sauce.
Cover the top with breadcrumbs, drizzle with warm dripping, and bake in a 350°F (175°C) oven for at least 1 hour.
If breadcrumbs brown too quickly, cover with greased paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meat and savoury flavour of the dish.
- All-purpose flour
- Thickens the stock into a smooth sauce that coats the beef.
- Beef dripping
- Adds rich fat and flavour for frying the onion and for browning the topping.
- Fine dry breadcrumbs
- Forms a crisp, browned crust over the top during baking.
- Tomato ketchup
- Adds sweetness and acidity that give the sauce a tangy flavour.
The step that matters
Watching the breadcrumb topping. Breadcrumbs brown quickly in a hot oven, so covering them with greased paper stops them burning before the dish is heated through during the long bake.
Swap the onion
How well each one fits the dish's main ingredients (beef, flour, pepper, tomato, ketchup, parsley, sauce):
- Capsicumfits better
- Carrotfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against beef, flour, pepper, tomato, ketchup, parsley, sauce. Candidates are from the same food group and used in at least 100 recipes.
