Green Corn Au Gratin

Oven, in the book's wordsA hot oven

Ingredients

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 the corn

  1. Cook the corn in boiling salted water for 10 minutes.

  2. Wrap the corn in a cloth.

  3. Once cool, shave off the kernels.

Make the filling

  1. Place the kernels in a sauté pan.

  2. Add a little strong Béchamel sauce.

  3. Simmer for 10 minutes until heated through.

  4. Season the mixture.

  5. Transfer to gratin dishes.

Bake and serve

  1. Sprinkle the top with fresh bread crumbs and small bits of butter.

  2. Bake in a hot oven at 400°F (200°C) until the top is a rich brown color.

  3. Serve hot in the same dish.

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

What each ingredient does

Fresh corn
Provides the sweet, starchy bulk of the dish.
Strong béchamel sauce
Adds moisture and a creamy binding that holds the kernels together.
Fresh bread crumbs
Form a crisp topping that browns in the oven for contrasting texture.
Butter
Adds richness and fat that helps the topping brown evenly.

The step that matters

Bake until the top is a rich brown. Browning on the crumbs and butter comes from dry heat driving Maillard reactions at the surface. If the oven is too cool the top stays pale and the filling heats slowly, while leaving it too long dries the sauce and hardens the crust.
