Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Cavitched Fish
Ingredients
Directions
Prepare the fish
Season the cleaned perch with cayenne pepper, black pepper, and salt.
Fry the perch in sweet oil until light brown.
Fry the sliced onions until brown.
Let the fish cool completely, then place them in a deep vessel and layer the fried onions on top.
Make the pickle and finish
In a pot, combine vinegar, fish liquor, mace, cloves, whole black pepper, minced garlic, cayenne pepper, mixed mustard, catsup, sweet oil, and salt.
Boil the mixture until it is flavorful from the spices.
Pour the hot or cold mixture over the fish, ensuring they are fully covered.
Taste the liquid after a day or two; adjust seasoning if necessary.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Perch
- Forms the main body of the dish, becoming firm and flaky when fried and then steeped.
- Vinegar
- Provides the sharp acidity that defines the pickle and helps preserve the fish.
- Sweet oil
- Fries the fish and onions, adding browning and a rich flavor.
- Onions
- Browned on top of the fish, adding sweetness and savory depth to the pickle.
- Mixed mustard
- Adds sharp, pungent flavor that balances the acidity of the vinegar.
The step that matters
Fry the perch until light brown. Frying sets the outside of the fish so it holds its shape in the hot pickle, while light browning adds flavor without drying the flesh. Overcooking toughens the fish and makes it fall apart.
Swap the mace
How well each one fits the dish's main ingredients (pepper, onion, vinegar, fish, clove, garlic, mustard):
- Tarragonfits better
- Thymefits better
- Capersfits better
- Macethe original
Fit is the average pairing score against pepper, onion, vinegar, fish, clove, garlic, mustard. Candidates are from the same food group and used in at least 100 recipes.
