Oysters on Toast

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Cover the bottom of a baking dish with toast.
Stew the oysters in their own liquor.
Place the oysters on the toast.
Thicken the liquor with a little flour.
Season with butter, coarse sea salt, and pepper.
Pour the mixture over the toast.

Bake and serve

Cover with a layer of cracker crumbs and dot with small pieces of butter.
Brown in the oven at 400°F (200°C) and serve hot.

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

What each ingredient does

Oysters: Provide the main seafood filling, cooked gently in their own liquor until tender.
Flour: Thickens the oyster liquor into a light sauce that clings to the toast.
Butter: Adds richness and moisture, and helps the top crumbs brown in the oven.
Cracker crumbs: Form a crisp, golden topping that browns in the oven.
Toast: Forms the base that soaks up the sauce and holds the oysters.

The step that matters

Brown in the oven at 400°F (200°C). Oysters are delicate and overcooking them makes them rubbery, so they should be heated only until the topping browns and the dish is hot. Watching the oven closely keeps the oysters tender while the crumbs turn golden.
