Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Pickle Oysters
Ingredients
Directions
Prepare the oysters
Select the largest oysters, drain off their liquor, and wash them in clean water. Pick out the pieces of shells that may be left.
Stew and pickle
Put them in a stew pan with water proportioned to the number of oysters, some salt, blades of mace, and whole black pepper. Stew them a few minutes.
Put them in a pot, and when cold, add as much pale vinegar as will give the liquor an agreeable acid.
Nutrition, whole recipe (rough)

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters (in the method)
- Form the main body of the dish, carrying the briny flavour into the pickle.
- Vinegar
- Adds acidity that sharpens the flavour and preserves the oysters in the liquor.
- Black pepper
- Contributes a mild, warm aromatic note to the pickling liquor.
The step that matters
Adding the vinegar. Vinegar should be added only once the oysters are cold, so the acid sets the flavour without overcooking the delicate flesh. Too much acid makes the liquor harsh, so it should be added until it is agreeable rather than strong.
Swap the mace
How well each one fits the dish's main ingredients (butter, flour, onion, pepper, vinegar):
- Garlicfits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against butter, flour, onion, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
