Clams on the Half Shell

Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Prepare the clams

  1. Carefully remove the razor clams from their shells without breaking them.

  2. Thoroughly clean the clams in cold water, removing all dark parts and the siphon.

  3. Drain well and chop the tender parts finely.

Make the filling

  1. Season with minced onion, tomato sauce, pepper, and salt.

  2. Mix in enough cracker crumbs to absorb the moisture, then wet with cream.

Bake and serve

  1. Fill the half shells with the mixture, dot with bits of butter, and sprinkle with minced parsley.

  2. Place the filled shells in a large baking pan and bake at 400°F (200°C) until brown.

  3. Serve immediately on hot plates.

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

What each ingredient does

Razor clams
Provide the main body of the filling and its briny, seafood flavour.
Cracker crumbs
Absorb moisture from the clams and cream to give the filling body.
Cream
Moistens the crumbs and keeps the filling tender rather than dry.
Butter
Adds richness and fat that helps the top brown in the oven.
Tomato sauce
Adds acidity and sweetness that season the filling.

The step that matters

Bake until brown. Baking too briefly leaves the clams underdone and the top pale, while overbaking toughens the clam meat. Watch for a light browning on top as the signal that it is done.

Swap the tomato

How well each one fits the dish's main ingredients (clam, onion, cream, butter, pepper, parsley, sauce):
