Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Stuffed Kidneys
Ingredients
Directions
Prepare
Split the kidneys lengthwise, leaving enough meat and skin on one side to serve as a hinge.
Rub the inside of the kidneys with melted butter.
Broil the kidneys, back downward, over a bright fire for 8 minutes.
Make the stuffing
Prepare a stuffing with bread crumbs, cooked salt pork, parsley, and butter, seasoned with pepper, salt, and onion juice.
Heat the stuffing in a saucepan set in boiling water, then stir in the lemon juice.
Assemble and serve
Fill the kidneys with the stuffing and secure the edges with a toothpick.
Pepper the stuffed kidneys and serve with sauce piquante.

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 dish, cooked by broiling until done through.
- Bread crumbs
- Bulk out the stuffing and soak up butter and juices for a soft texture.
- Salt pork
- Adds salty, savory fat that flavours the stuffing.
- Butter
- Adds richness and moisture to the kidneys and the stuffing.
- Lemon juice
- Adds acidity that brightens the rich kidney and pork flavours.
The step that matters
Broil the kidneys, back downward, over a bright fire. Kidneys cook quickly and turn tough and dry if overcooked. A hot fire sears the cut surface, and the time should be watched closely so the centre stays tender.

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