Toast with Olive Oil and Cheese

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Dip the toast in olive oil and arrange on a dish.

  2. Sprinkle grated Parmesan cheese, pepper, and lemon juice over the toast.

Bake and serve

  1. Place in a 400°F (200°C) oven for a few minutes until the cheese melts.

  2. Serve immediately after removing from the oven.

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

What each ingredient does

Olive oil
Coats the toast, adding richness and helping it crisp and brown in the oven.
Grated parmesan cheese
Melts into a savory, golden topping that binds to the toast.
Lemon juice
Adds acidity that brightens the rich oil and cheese.

The step that matters

Baking until the cheese just melts. Cheese that is left too long in the oven can darken, turn greasy, and become tough or burnt. Removing it as soon as the cheese melts keeps it smooth and golden.

Swap the lemon

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

  1. Lemonthe original
  2. Plumfits about as well
  3. Cherryfits less well
  4. Limefits less well

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