Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Stewed Kidneys
Ingredients
Directions
Prepare the kidneys
Skin the kidneys and remove the fat without cutting them.
Slice the kidneys into pieces about ¼ inch thick.
Mix parsley, thyme, salt, pepper, and cayenne in a plate.
Sprinkle the mixture over the sliced kidneys.
Cook the stew
Melt butter in a pan and add the kidneys, browning them quickly on both sides.
Dredge flour over the kidneys and shake to prevent burning.
Pour in stock and simmer for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Form the main body of the stew and provide its meaty texture.
- Butter
- Adds fat for browning the kidneys and carries flavour through the dish.
- Flour
- Coats the kidneys and thickens the stock into a light sauce.
- Stock
- Provides the liquid that becomes the stew and softens the kidneys as it simmers.
The step that matters
Browning the kidneys quickly. Searing the kidneys quickly over high heat builds colour and flavour on the surface. Overcooking them makes the meat tough and rubbery, so they should be seared briefly and not left in the pan.
Swap the thyme
How well each one fits the dish's main ingredients (parsley, pepper, butter, flour):

Fit is the average pairing score against parsley, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
