Preserved Oysters

Ingredients

Directions

Prepare the oysters

  1. Open the oysters carefully, separating the shells without cutting the meat.

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

  3. Pound the oysters and rub them through a fine sieve.

  4. Return the mixture to the mortar and add 7 ounces of dried flour to form a paste.

  5. Roll out the paste to about ½ inch thick and cut into squares.

Dry and preserve

  1. Place the squares in a Dutch oven to dry gently, turning every half hour for about 4 hours.

  2. Once dried, pound the squares finely and sift them into bottles, sealing them tightly.

Make the sauce

  1. To make sauce, melt 1 ounce of butter in a pan, add 3 teaspoons of water powder and 1 tablespoon of milk.

  2. Heat on low, stirring until it boils, and season with salt.

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

What each ingredient does

Oysters
Provide the main flavour and the protein that becomes the preserved paste.
Dried flour
Binds the pounded oyster mixture into a paste that can be rolled and cut.
Butter
Adds fat and richness to the sauce.
Milk
Adds moisture and creaminess to the sauce.

The step that matters

Drying the squares gently. Drying slowly at low heat removes moisture evenly so the squares harden without browning or cooking through. Turning them keeps every side drying at the same rate.
