Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Carp with Beer
Ingredients
Directions
Prepare
Scale and split the carp in two, removing as many bones as possible.
Butter the bottom of a flat stewpan and layer with sliced onions.
Place the carp pieces on top, removing the gall-stone and cutting the head in two.
Braise
Season the fish with salt, add chopped celery, parsley, thyme, peppercorns, cloves, and diced gingerbread.
Moisten the fish with beer and bring to a boil over high heat for 7-8 minutes.
Reduce heat to moderate and finish cooking the fish until the sauce thickens and is well-colored.
Serve
Serve the carp on a hot dish, skimming the fat from the sauce and pouring it over the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Forms the body of the dish; its protein firms and turns opaque as it cooks.
- Beer
- Provides the cooking liquid that braises the fish and flavors the sauce.
- Butter
- Adds fat and richness to the base layer and carries flavor from the aromatics.
- Onion
- Softens and sweetens as it cooks, building a mellow aromatic base for the sauce.
- Gingerbread
- Its starch helps thicken the sauce, and its sugars add sweetness and browning.
The step that matters
Reducing the heat after the boil. Once the liquid has boiled hard, dropping to moderate heat lets the fish cook through gently without breaking apart, while the sauce reduces and thickens slowly and browns evenly.
Swap the onion
How well each one fits the dish's main ingredients (butter, celery, parsley, clove, beer):
- Carrotfits better
- Mustardfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against butter, celery, parsley, clove, beer. Candidates are from the same food group and used in at least 100 recipes.
