Roasted Oysters

Oven, in the book's wordsA hot oven

Ingredients

large fresh oysters
butter
cayenne pepper
lemon

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Wash the oyster shells until they are very clean.
Place the oysters in a dripping pan with the round shell down.

Roast and serve

Roast in a hot oven at 400°F (200°C) for about 20 minutes.
When ready to eat, remove the top shell.
Add a small piece of butter, a dash of cayenne pepper, and a few drops of fresh lemon juice on each oyster.

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

What each ingredient does

Oysters: Provide the main ingredient, which cooks in its shell and becomes tender from the dry heat.
Butter: Adds richness and moisture as it melts over the hot oyster meat.
Lemon: Adds acidity that brightens the rich flavor of the oysters and butter.
Cayenne pepper: Adds gentle heat and aroma to the finished oysters.

The step that matters

Roast in a hot oven at 400°F (200°C) for about 20 minutes. Oysters are delicate and overcooking them makes the meat tough and shrunken. Watching the time keeps the flesh plump and juicy while the shell stays hot enough to cook the oyster through.
