Why it works: Pepper and carrot match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Calf's Liver, a LA Bourgeoise
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook the liver
Melt the butter in a stewpan over low heat until browned.
Season the liver with salt, pepper, and nutmeg, then place it in the butter.
Add the sliced onions and carrots when the liver is half cooked.
Cover the stewpan and bake in the oven at 300°F (150°C) for 2 to 3 hours, ensuring the liver does not stick to the pan.
Once cooked, transfer the liver to a dish and keep warm.
Make the gravy
Pour the gravy through a colander to remove grease.
In another pan, melt the lard and stir in the flour.
Gradually add the gravy and let it simmer uncovered for 1 minute.
Serve
Pour the gravy over the liver and arrange the carrots and onions around it.
Add capers or pickles if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Is the main dish, cooked slowly so it becomes tender and cooked through.
- Butter
- Fat for browning the liver and adding rich flavour to the pan.
- Flour
- Thickens the lard and gravy into a smooth sauce.
- Onions
- Soften and sweeten as they cook, adding flavour to the gravy.
- Carrots
- Soften and sweeten as they cook, adding flavour to the gravy.
The step that matters
Keep the liver from sticking and overcooking during the long bake. Liver is lean and delicate, and over a long, slow bake it can dry out or stick to the pan. Covering the pan and keeping the heat low helps it stay moist and tender.
Swap the onion
How well each one fits the dish's main ingredients (liver, butter, flour, pepper, nutmeg, red wine, carrot):
- Shallotfits better
- Parsnipfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against liver, butter, flour, pepper, nutmeg, red wine, carrot. Candidates are from the same food group and used in at least 100 recipes.
