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 and Oysters
Ingredients
Directions
Prepare
Broil the steak as usual.
In a stewpan, heat 1 quart of oysters with a little of their liquor until boiling. Skim off any foam that rises.
Make the sauce
Stir in 3 ounces of butter mixed with 1 tablespoon of sifted flour.
Let it boil for 1 minute until it thickens.
Serve
Pour the oyster mixture over the steak and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and the briny, savory character of the dish.
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
- Flour
- Thickens the butter and oyster liquor into a smooth sauce as it boils.
- Beefsteak
- Serves as the main cooked meat base the oyster sauce is poured over.
The step that matters
Boiling the sauce after adding the butter and flour. Flour thickens only when it reaches a boil and stays there briefly, so the sauce must boil for the full minute to set properly and avoid a thin, floury taste.
“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.
