Preserved Oysters

Ingredients

Directions

Prepare the oyster paste

  1. Open the oysters carefully, avoiding cutting them except to separate the gristle from the shells.

  2. Place the oysters in a mortar and add the coarse sea salt.

  3. Pound the oysters until smooth.

  4. Rub the mixture through a fine sieve back into the mortar.

  5. Add enough dried flour to form a paste.

  6. Roll the paste out to about 1/8 inch thick.

  7. Cut the paste into 1-inch squares.

Dry and store the powder

  1. Place the squares in a Dutch oven to dry gently.

  2. Turn the squares every half hour.

  3. Once they begin to dry, crumble them.

  4. Continue drying for about 4 hours.

  5. Pound the dried pieces finely.

  6. Sift the powdered oyster.

  7. Store the powder in bottles, sealing them tightly.

Make the sauce

  1. Melt the butter in a saucepan.

  2. Add the oyster powder and milk.

  3. Stir until it boils.

  4. Season the sauce with salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Provide the main oyster flavour and the body of the paste.
Dried flour
Binds the pounded oysters into a paste that can be rolled and dried.
Butter
Adds fat and richness to the sauce.
Milk
Makes the sauce creamy and liquid when combined with the powder.
Oyster powder
Concentrates oyster flavour into the sauce.

The step that matters

Drying the squares gently. Turning the squares regularly and drying them gently lets moisture leave evenly, so the pieces dry without scorching or hardening unevenly before they are pounded into powder.
