Canapes of Fresh Cod Roe

Oven, in the book's wordsA sharp oven

Ingredients

Directions

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

Prepare the roe

Wash the cod roe and place it in a saucepan with enough cold water to cover it.
Simmer the roe for 5 to 8 minutes, depending on thickness.
Remove the roe from the water, dry it, and pound it into a smooth paste.

Make the topping

Mix in the whipped cream and season with salt, cayenne, and strained lemon juice.

Assemble and serve

Cut the bread into rounds the size of a half-dollar and fry them in butter or dripping until light brown.
Top each crouton with a small heap of the fish and cream mixture.
Heat the canapés in a hot oven (400°F / 200°C) until very hot.
Garnish with chopped truffle, lobster coral, or parsley before serving.

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

What each ingredient does

Cod roe: Forms the main fish paste and gives the canapés their rich, savory flavor.
Thick cream: Adds moisture and softness to the fish paste, making it smooth and spreadable.
Bread: Provides a crisp, golden base that holds the topping.
Lemon juice: Adds acidity that brightens the rich fish flavor.

The step that matters

Simmering the roe. Simmering for too long makes cod roe firm and grainy, while too short a time leaves it underdone. Timing by thickness helps it set just enough to pound into a smooth paste.
