Why it works: Onion and horseradish match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,784 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Fillet of Beef, Hussar Fashion
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Drain the fillet.
Trim the fillet.
Slice it thinly.
Make the horseradish mixture
Chop the onions.
Fry them in butter until nicely colored.
Moisten the onions with 1 cup of broth.
Reduce to a glaze over moderate heat.
Add 1 1/2 cups of brown sauce to the onions.
Bring to a boil.
Remove from heat.
Mix in the grated horseradish.
Assemble and bake
Reshape the fillet on a serving dish.
Alternate the slices with the horseradish mixture.
Cover the top with it.
Sprinkle with bread crumbs.
Sprinkle more bread crumbs on top.
Moisten the bottom of the dish with light brown sauce.
Bake in a 350°F (175°C) oven.
Baste occasionally.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox fillet
- Provides the tender, sliceable meat that forms the base of the dish.
- Onions
- Caramelized in butter, they add sweetness and a deep savory flavor to the filling.
- Brown sauce
- Adds richness and moisture to the onion mixture so it stays saucy under the bread crumbs.
- Horseradish
- Contributes a sharp, pungent bite that balances the richness of the meat and sauce.
- Bread crumbs
- Form a crisp, browned crust on top during baking.
The step that matters
Reduce the onions to a glaze. Cooking the onions until deeply colored and reduced concentrates their sugars and flavor; if they stay wet or pale, the filling will taste flat and watery.
Swap the horseradish
How well each one fits the dish's main ingredients (onion, butter, sauce, bread):
