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, once dried and powdered, the savoury base of the preserve.
Dried flour
Binds the oyster mixture into a paste that can be rolled and cut into squares.
Butter
Adds richness and fat to the finished sauce.
Milk
Adds moisture and body to the sauce when combined with the oyster powder.

The step that matters

Dry the squares gently. Gentle, low-heat drying removes moisture slowly so the squares dry evenly without scorching. Turning them every half hour exposes all sides to air so they dry uniformly and keep well.
