Oyster Rarebit

Ingredients

Directions

Prepare the oysters

  1. Clean and remove the hard muscles from the oysters.

  2. Parboil the oysters in their own liquor until the edges curl, then transfer to a hot bowl.

Make the rarebit

  1. In a chafing dish, melt the butter and add the cheese, salt, mustard, and cayenne.

  2. While the cheese is melting, beat the eggs slightly and mix in the oyster liquor.

  3. Gradually combine the egg mixture with the melted cheese, then add the oysters.

  4. Serve immediately over hot toast.

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

What each ingredient does

Oysters
Provide the main flavor and tender texture of the dish.
Cheese
Melts into a smooth, rich sauce that coats the oysters.
Eggs
Thicken the cheese mixture into a creamy, custard-like sauce as they cook gently.
Butter
Melts with the cheese to add richness and a smooth, fluid base.

The step that matters

Combine the egg mixture with the melted cheese gradually. Adding the beaten eggs slowly, while the cheese is warm and stirred, lets the egg proteins blend in gently. Adding them all at once or over high heat can scramble them and leave the sauce grainy.

Swap the mustard

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

  1. Asparagusfits better
  2. Potatofits about as well
  3. Cucumberfits about as well
  4. Mustardthe original

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