Why it works: Parsley and shallot 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 ↓
Sheep’s Kidneys Stewed in Port Wine
Ingredients
Directions
Prepare
Trim off the pith and skin from each kidney and cut them into pieces.
Season the kidneys with white pepper, cayenne, coarse sea salt, parsley, and shallot.
Cook
Melt the butter in a saucepan over medium heat until it begins to dissolve.
Add the kidneys and shake the pan to brown them slightly.
Pour in the stock, jelly, and port wine, then cover the pan with a lid.
Simmer gently for twenty minutes without removing the lid.
Serve immediately on a hot dish.

Butter and flour 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
What each ingredient does
- Kidneys
- Provide the main meat, which becomes tender when simmered gently in liquid.
- Butter
- Adds fat and richness and helps brown the kidneys in the pan.
- Flour
- Thickens the cooking liquid into a light sauce as it simmers.
- Port wine
- Adds sweetness and depth of flavour to the sauce as it reduces.
- Stock
- Forms the liquid base that cooks the kidneys and carries the flavour.
- Jelly
- Adds sweetness and body to the sauce, giving it a glossy finish.
The step that matters
Simmer gently with the lid on. Keeping the heat low and the lid on holds the liquid steady, so the kidneys cook through and turn tender without toughening. Boiling hard or lifting the lid lets the liquid evaporate and the meat dry out and firm up.
Swap the white pepper
How well each one fits the dish's main ingredients (parsley, shallot, butter, flour, port wine):
- Capersfits better
- Tarragonfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against parsley, shallot, butter, flour, port wine. Candidates are from the same food group and used in at least 100 recipes.
