Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Oysters on Toast
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour to make a roux, cooking for 1-2 minutes.
Gradually add the milk and oyster liquor, stirring until thickened.
Finish and serve
Chop the oysters and warm them through in the sauce.
Serve the oyster mixture on hot, unbuttered toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the roux with fat and adds a rich flavour to the sauce.
- Flour
- Thickens the sauce when cooked with butter to form a roux.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats.
- Oysters
- Provide the main ingredient and a briny flavour that the sauce carries.
- Oyster liquor
- Adds concentrated oyster flavour and salinity to the milk sauce.
The step that matters
Thickening the sauce. Flour must be cooked in the butter long enough to lose its raw taste, and milk must be added gradually while stirring so lumps do not form. Adding the liquid too fast or without stirring leads to a lumpy, uneven sauce.
“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.
