Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Assemble

  1. Preheat the oven to 350°F (175°C).

  2. Place the diced potatoes in a shallow serving dish.

  3. Add the cheese and white sauce over the potatoes.

Top and bake

  1. Cover with cracker crumbs moistened with melted butter.

  2. Bake until the crumbs are browned.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Potatoes
Form the bulk of the dish, providing a soft, starchy body under the topping.
White sauce
Adds moisture and creaminess that coats the potatoes as they bake.
Cheese
Melts into the sauce, adding richness and savory flavor.
Cracker crumbs
Form a crisp topping that browns in the oven.
Butter
Moistens the cracker crumbs and helps them brown evenly.

The step that matters

Bake until the crumbs are browned. Browning depends on heat and time. Underbaking leaves the topping pale and soft, while overbaking can dry the sauce and harden the cheese. Look for an even golden top.

Swap the potato

How well each one fits the dish's main ingredients (sauce, cheese, butter):

  1. Mustardfits better
  2. Tomatofits about as well
  3. Onionfits about as well
  4. Potatothe original

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