Nut and Cheese Koast

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.

Prepare

  1. Cook the onions in the butter with a little water until tender.

Mix and bake

  1. Mix the grated cheese, walnuts, lemon juice, bread crumbs, and cooked onions.

  2. Moisten the mixture with the water used to cook the onions.

  3. Pour the mixture into a shallow baking dish.

  4. Bake until browned in a 350°F (175°C) oven.

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

What each ingredient does

Grated cheese
Melts and binds the mixture while adding rich flavor and savory depth.
Bread crumbs
Absorb liquid and give the casserole body and a light, set texture.
English walnuts
Add crunch and a toasty, slightly bitter note that contrasts the cheese.
Butter
Adds fat and richness, helping the onions soften and carry flavor.

The step that matters

Moisten the mixture with the onion cooking water. The mixture must be damp enough for the crumbs to soften and hold together. Too dry, it bakes crumbly; too wet, it turns soggy and does not brown well.

Swap the onion

How well each one fits the dish's main ingredients (cheese, butter, walnut, lemon, bread, pepper):

  1. Capsicumfits better
  2. Spinachfits better
  3. Asparagusfits better
  4. Onionthe original

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