Potatoes, with Cheese Sauce

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.

Make the sauce

  1. In a saucepan, stir the pepper, salt, nutmeg, beaten eggs, and half the cheese into the hot drawn butter.

  2. Heat while stirring constantly until it thickens.

Assemble and bake

  1. Layer mashed potatoes in a flat dish, shaping them to fit.

  2. Cover with the cheese sauce.

  3. Repeat with another layer of potatoes and sauce until you form a mound on top.

  4. Coat the top with sauce, then sprinkle with the remaining cheese and cracker dust.

  5. Arrange the fried bread triangles around the base.

  6. Bake in a 400°F (200°C) oven until browned.

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

What each ingredient does

Eggs
Beaten eggs thicken the hot butter sauce as they set, binding it into a spoonable custard.
Potatoes
Mashed potatoes form the bulk of the casserole, giving a soft, moist body under the sauce.
Drawn butter
Hot butter carries the flavour and richness and helps the sauce stay smooth and glossy.
Cheese
Dry grated cheese adds savoury flavour and helps the topping brown in the oven.

The step that matters

Heating the egg sauce. Stirring constantly keeps the beaten eggs from scrambling in the hot butter. Gentle, steady heat lets them thicken smoothly into a sauce rather than curdling into lumps.

Swap the nutmeg

How well each one fits the dish's main ingredients (potato, milk, butter, cheese, egg, pepper, bread):

  1. Parsleyfits about as well
  2. Nutmegthe original
  3. Thymefits about as well
  4. Cinnamonfits less well

Fit is the average pairing score against potato, milk, butter, cheese, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
