Ingredients: 4 to 6 large oysters; Coarse sea salt; Black pepper; Nutmeg; 2 tablespoons finely chopped parsley; 2 tablespoons finely chopped mushrooms; 2 tablespoons bread crumbs; 1 tablespoon butter

Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

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

Dry the oysters on a napkin.
Place them in cleaned oyster shells or a silver shell.

Season and bake

Season with salt, pepper, nutmeg, parsley, and mushrooms.
Cover the oysters with bread crumbs and top with butter.
Bake in a hot oven at 400°F (200°C) until golden.
Serve hot.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Oysters: Form the main body of the dish, becoming tender when heated through.
Bread crumbs: Form a crisp golden topping that browns in the oven.
Butter: Adds fat that helps the crumb topping brown and adds richness.
Mushrooms: Add savoury, earthy flavour and moisture to the filling.

The step that matters

Bake until golden, not longer. Oysters cook quickly and turn rubbery when overheated, while the crumbs and butter need enough heat to brown. Watching for golden color signals doneness before the oysters toughen.

Swap the nutmeg

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