Eggs, with Black Butter

Ingredients

Directions

  1. Melt the butter in a frying pan over medium heat.

  2. Crack the eggs into a plate without breaking the yolks.

  3. Gently slide the eggs into the pan and season with salt and pepper.

  4. Do not let the yolks harden; use a hot fry spoon to crust them slightly.

  5. Serve with a drizzle of vinegar.

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

What each ingredient does

Butter
Melts and browns in the pan, adding a nutty, toasted flavour to the eggs.
Eggs
Set into the main dish, with runny yolks giving a rich, creamy texture.
Vinegar
Adds a sharp acidity that cuts through the richness of the butter and yolks.

The step that matters

Keep the yolks runny. Egg yolks set and thicken once they get hot enough, so over-cooking turns them firm and dry. Gentle heat and a quick crust with a hot spoon keep the yolks soft while the whites set.
