Why it works: Oyster and anchovy work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 603 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Oyster Soup
Ingredients
Directions
Make the stock
In a pot, combine the stock, onion, salt, and peppercorns. Boil until reduced.
Skim and strain the mixture. Return 1 quart to the pot with the bay leaf and oyster liquor.
Thicken and finish
Stir in flour mixed with water to form a smooth paste. Bring to a boil.
Add the boiled cream and anchovy essence. Stir well.
If using fresh oysters, add their liquor to the stock, remove gills, and simmer to extract flavor.
Serve
Heat a metal strainer in the boiling stock, add oysters for 3 seconds, then transfer to a soup tureen.
Pour the soup over the oysters and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup into a smooth, body-rich liquid when mixed with water and boiled.
- Cream
- Adds richness and a smooth, mellow texture to the finished soup.
- Oyster liquor
- Supplies the concentrated briny, savory flavor that defines the soup.
- Cod or mutton stock
- Forms the liquid base that carries all the other flavors.
- Anchovy essence
- Adds a deep savory, salty note that enhances the seafood flavor.
The step that matters
Heating the oysters in the strainer. Oysters overcook quickly and turn tough and rubbery. A brief 3-second dip in the boiling stock is enough to warm them through while keeping them tender.
Swap the onion
