Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Kidneys À LA Fifth Avenue with Wine Sauce
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Remove the membranes from the kidneys and cut them into slices.
Make the sauce
In a skillet, melt the butter and sauté the chopped onion until golden.
Add the kidney slices and cook until browned.
Sprinkle flour over the mixture and stir well.
Pour in the red wine, season with salt and pepper, and simmer for 10 minutes.
Bake
Transfer to a baking dish and bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef kidneys
- Provide the main meat, which browns and becomes tender when cooked briefly.
- Red wine
- Adds acidity and depth to the sauce while simmering.
- Butter
- Carries the onion's browning and adds richness to the pan.
- Flour
- Thickens the pan juices into a smooth sauce.
The step that matters
Browning the kidney slices. Kidney that is overcooked turns tough and rubbery, so brown it quickly over steady heat. Browning builds flavour, but the slices finish cooking in the oven and the wine sauce, so stop before they are fully firm.
Swap the onion
How well each one fits the dish's main ingredients (beef, red wine, butter, flour, pepper):
- Shallotfits better
- Potatofits about as well

- Onionthe original
Fit is the average pairing score against beef, red wine, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
