Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Oysters on Toast
Ingredients
Directions
Prepare
Wash the oysters and reserve the liquor.
Make the sauce
In a saucepan, bring the oyster liquor to a boil with the milk, salt, and pepper.
In a small bowl, mix the flour with the cold milk until smooth, then add to the boiling mixture to thicken.
Drop in the oysters and boil again briefly.
Serve
Pour the mixture over the toasted bread and 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 texture of the dish.
- Flour
- Thickens the milk mixture into a smooth, cohesive sauce.
- Milk
- Adds creaminess and body to the sauce.
- Toast
- Serves as the base that holds the creamy oyster mixture.
The step that matters
Adding the flour mixture to the boiling liquid. Flour must be mixed smooth with cold milk first, because dry flour dropped into hot liquid clumps and cannot thicken evenly. Stirring keeps the starch dispersed so the sauce thickens smoothly.
