Cheese and Onions

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 the onions

  1. Slice the onions very thin.

  2. Place them on a dish with a little water, adding pepper and coarse sea salt.

  3. Cover and set in a 350°F (175°C) oven until tender.

Top and toast

  1. Lay thin slices of cheese over the onions.

  2. Toast all together in the oven until the cheese is melted.

  3. Serve immediately.

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

What each ingredient does

Cheese
Melts into a creamy, browned topping that carries the dish's richness.
Onions
Soften under gentle covered heat to become sweet and tender, forming the base.

The step that matters

Cover and set in the oven until tender. The onions must cook covered in a little water until fully soft. Covering traps steam so they cook evenly, and underdone onions stay sharp and fibrous under the melted cheese.

Swap the onion

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

  1. Capsicumfits better
  2. Mustardfits better
  3. Tomatofits better
  4. Onionthe original

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