Asparagus on Toast

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the asparagus

  1. Tie the asparagus with soft string and cut away the woody ends.

  2. Cook the asparagus in salted boiling water for about 20 minutes.

Assemble the toast

  1. Dip each slice of crustless toast in the asparagus cooking water.

  2. Butter the toast generously while hot and place on a heated dish.

  3. Drain the asparagus and arrange it on the toast.

  4. Season with pepper, salt, and more butter.

  5. If desired, break an egg over each serving and place in a 400°F (200°C) oven until the whites are firm.

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

What each ingredient does

Asparagus
Forms the main topping and adds its own fresh, green flavor to the toast.
Crustless bread slices
Provide the base that soaks up cooking water and butter, giving a soft, moist texture.
Butter
Adds richness and fat, carrying flavor and helping the hot toast brown lightly.
Eggs
Optional topping whose proteins set when baked, firming the whites over the toast.

The step that matters

Egg whites in the oven. Egg whites set as their proteins coagulate with heat, while yolks stay runnier. Baking only until the whites are firm keeps the yolks soft and avoids a rubbery texture.

Swap the asparagus

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

  1. Capsicumfits about as well
  2. Asparagusthe original
  3. Chivefits about as well
  4. Spinachfits less well

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