Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and 124,287 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Oyster Sauce
Ingredients
Directions
Make the oyster broth
Boil ½ pint of small oysters with their liquor in 1 pint of water until the flavor is well extracted.
Strain the mixture, pressing the juice from the oysters.
Finish the sauce
Add 1 pint of small fresh oysters and stew until puffed.
Remove the oysters, skim the liquid well.
In a separate pan, melt 2 tablespoons of butter.
Add 2 tablespoons of flour to the melted butter to make a drawn butter.
Put the cooked oysters back into the sauce.
Heat the sauce thoroughly.
Serve.

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, when stewed, the body of the sauce.
- Butter
- Enriches the sauce with fat and richness when melted with flour.
- Flour
- Thickens the butter into a roux that gives the sauce body.
The step that matters
Adding the flour to the melted butter. Flour must be stirred into melted butter so it cooks into a smooth roux. Added in lumps or to a too-hot pan, it clumps and the sauce turns grainy instead of thick and even.
