Why it works: Flour and parsley are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 16,675 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Entree of Crimped Cod
Ingredients
Directions
Prepare the cod
Boil a pot of salted water.
Add the cod and boil for 10 minutes.
Remove the cod and let it cool, then flake it into pieces.
Batter and fry
In a bowl, mix flour, sweet oil, white wine, and a little salt to make a batter.
Heat lard in a frying pan until hot.
Dip each flake of cod into the batter and fry until golden brown.
Drain on paper towels and serve with fried parsley and oyster sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crimped cod
- Forms the main protein, which turns firm and flaky after boiling and frying.
- All-purpose flour
- Forms the batter that coats the cod and crisps into a golden crust when fried.
- Sweet oil
- Adds fat to the batter, helping it brown and stay tender rather than tough.
- White wine
- Adds acidity and aroma to the batter, and its alcohol evaporates as it fries.
- Lard
- Frying fat that conducts heat evenly and gives the coating a crisp, browned surface.
The step that matters
Let the cod cool before battering. Cod that is still hot or wet will release steam and water into the batter, making it soggy and causing it to slide off in the hot fat. Cooling and drying the flakes helps the batter cling and crisp.
Swap the parsley
How well each one fits the dish's main ingredients (flour, white wine, oyster, sauce):
- Capersfits better
- Jalapenofits better
- Tarragonfits better
- Parsleythe original
Fit is the average pairing score against flour, white wine, oyster, sauce. Candidates are from the same food group and used in at least 100 recipes.
