Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Remove skins and cores from the kidneys and cut them into dice.
Heat butter in a pan, fry the shallot slightly, then add parsley and kidneys. Cook gently for 5 minutes.
Drain the butter and use it instead of salad oil for the batter if preferred.
Prepare the brown sauce, cool slightly, then mix it with the egg yolks while stirring continuously.
Add the sauce to the kidneys, season to taste, and stir by the fire until the yolks thicken. Transfer to a plate to cool.
Cut the caul into 3-inch squares. Make a smooth batter with flour, water, salt, and salad oil or butter, then fold in the whipped egg white.
Once the mixture is cold, divide it into small portions, enclose them in caul pieces, dip in batter, and fry in hot fat until brown.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Swap the parsley
How well each one fits the dish's main ingredients (flour, butter, egg, shallot, sauce):
- Capersfits better
- Tarragonfits about as well
- Parsleythe original
- Nutmegfits about as well
Fit is the average pairing score against flour, butter, egg, shallot, sauce. Candidates are from the same food group and used in at least 100 recipes.
