Why it works: Flour and butter 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 ↓
Oysters, Fried
Ingredients
Directions
Prepare the oysters
Open the oysters and simmer them for 2 minutes in their own liquor.
Dry the oysters with a cloth and remove the gills.
Make the batter
In a bowl, mix the flour, egg yolk, clarified butter, and lukewarm water until smooth.
Add a pinch of salt and let the batter stand in a cool place for 2 hours.
Stir in the well-whisked egg whites.
Fry and serve
Dip each oyster in the batter and drop them into boiling fat.
Fry until crisp and brown, about 7 to 8 minutes.
Drain on a cloth and serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the batter's structure, which clings to the oysters and fries up crisp.
- Egg whites
- Whisked egg whites add air that keeps the fried batter light and puffed.
- Egg yolk
- Enriches the batter and helps it bind smoothly for an even coating.
- Clarified butter
- Adds fat that promotes browning and a rich flavor in the crust.
- Oysters
- The main ingredient, whose delicate flesh is cooked gently inside the crisp coating.
The step that matters
Drop the oysters into boiling fat. The fat must be hot enough to set the batter quickly. If it is too cool, the batter absorbs oil, turns greasy, and the oysters overcook before the coating browns.
