Cream Oysters on the Half Shell

Oven, in the book's wordsA hot oven

Ingredients

1 cup hot water
1 cup milk
1 cup thick cream
¼ teaspoon coarse sea salt
2 tablespoons butter
2 heaping tablespoons rice flour, corn starch, or arrowroot
a little cold milk
12 large oysters, cleaned and shells washed and buttered

Directions

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

Make the cream

Combine hot water, milk, thick cream, and salt in a saucepan.
Place the saucepan in a kettle of hot water and heat until just boiling.
Stir in butter.
Mix flour or starch with a little cold milk. Stir the flour mixture into the saucepan.
Stir and beat the prepared cream well.

Assemble and bake

Place a large oyster in each buttered shell.
Arrange the oysters in a baking pan, propping them up with pebbles or bits of shell.
Fill each shell with the prepared cream.
Bake in a hot oven (400°F / 200°C) for 5 to 6 minutes until brown.
Serve in the shell.

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

What each ingredient does

Thick cream: Adds richness and body, giving the filling a creamy texture.
Rice flour, corn starch, or arrowroot: Thickens the cream so it sets around the oysters rather than running off.
Butter: Adds fat and flavor to the cream and coats the shells.
Oysters: Provide the main seafood flavor and tender body under the cream.

The step that matters

Stirring the thickened cream. Starch must be fully dispersed and heated to thicken; stirring it smooth and brought to a boil keeps lumps out and gives the cream a uniform set in the oven.
