Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Beefsteak Roast
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the steak
Preheat the oven to 400°F (200°C).
Sear the steak all over in a hot skillet with enough butter to prevent sticking.
Transfer the steak to a small roasting pan and spread with bacon fat.
Dust with salt and pepper, then bake for 30 minutes.
Make the sauce
In the pan, add flour to the drippings and let it brown.
Slowly add boiling water, stirring until combined.
When boiling, add currant jelly (or horseradish) and strain the sauce.
Serve
Serve the steak hot with the sauce or its own juices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Club steak
- Provides the main cut of meat, whose thickness allows a seared outside and tender interior.
- Butter
- Fat for searing that helps brown the surface and keeps the steak from sticking.
- Bacon fat or dripping
- Adds fat and savory flavor that promotes browning on the outside of the roast.
- Flour
- Thickens the pan drippings into a sauce as it cooks and browns in the fat.
- Currant jelly
- Adds sweetness and fruity acidity that balances the rich meat drippings.
The step that matters
Add the flour to the drippings and let it brown. Flour must cook in the hot fat until lightly browned before liquid is added. This toasts the starch, deepens flavor, and keeps the sauce from tasting raw or lumpy.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (butter, pepper, flour):
- Lemonfits better
- Limefits better
- Raisinfits better
- Currantthe original
Fit is the average pairing score against butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
