Eggs and Mushrooms

Oven, in the book's wordsA hot oven

Ingredients

Directions

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

Prepare the mushrooms

  1. Trim the ends and stalks from the mushrooms and soak them in water with a little lemon juice.

  2. Drain the mushrooms and onion (if using), then slice them.

Cook and bake

  1. Fry the mushrooms and onion in butter until tender.

  2. Transfer the mushrooms to a dish.

  3. Carefully break the eggs on top, avoiding breaking the yolks.

  4. Season with salt and pepper.

  5. Sprinkle with browned breadcrumbs.

  6. Bake in a hot oven (400°F / 200°C) until the eggs are set.

  7. Serve immediately.

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

What each ingredient does

Eggs
Set when baked, forming the body of the dish and holding it together.
Button mushrooms
Release moisture and savoury flavour as they soften in the butter.
Butter
Fat that softens the mushrooms and onion and carries flavour.
Browned breadcrumbs
Add a crisp, golden top through browning in the oven.

The step that matters

Breaking the eggs on top. Keeping the yolks intact matters because the whites set around them while the yolks stay soft. Breaking a yolk spreads yolk through the whites and changes the texture of the finished dish.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (mushroom, butter, egg, pepper):

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

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