Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Stewed Kidneys and Macaroni
Ingredients
Directions
Prepare
Boil water in a pot and season with salt.
Add macaroni and cook for about 20 minutes until soft but not broken.
While the macaroni cooks, skin and halve the kidneys.
Make the stew
In a frying pan, melt butter and add the kidneys, tossing for 2-3 minutes.
Sprinkle with parsley, pepper, and salt, then pour in the stock.
Bring to a boil, then cover and simmer on low heat for 5 minutes.
Transfer the kidneys to a hot serving dish, boil the gravy, and pour over the kidneys.
Serve
Arrange the macaroni around the dish as a border and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Provide the main meaty texture and rich flavour of the stew.
- Butter
- Adds fat for richness and helps sear the kidneys in the pan.
- Stock
- Forms the liquid gravy that moistens the kidneys and carries flavour.
- Macaroni
- Adds a soft, starchy base that absorbs some of the rich gravy.
The step that matters
Simmering the kidneys after adding stock. Kidneys turn tough and rubbery if overcooked, so keep the heat low and the simmer short. Boiling hard after adding stock can toughen the meat and reduce the gravy unevenly.
