Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Braised Calf's Liver
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the liver
Lard the liver in three rows and place strips of salt pork on top of the liver.
In a baking pan, combine carrot, turnip, onion, and salt pork.
Place the liver on top of the vegetables.
Braise
Add stock or hot water, salt, peppercorns, and parsley.
Cover with another pan.
Cook at 350°F (175°C) for 2.5 hours, basting often.
Add more stock or water if necessary.
Make the gravy
Melt butter in a saucepan.
Stir in flour until brown.
Gradually stir in 1 cup of strained stock from the pan.
Season with additional salt and pepper if needed.
Pour the gravy around the liver.

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, becoming tender and firm as it braises slowly in liquid.
- Salt pork
- Adds fat and savory flavor that keeps the lean liver moist during long cooking.
- Butter
- Provides fat for the gravy and carries flavor when cooked with flour.
- Flour
- Thickens the gravy by binding with the melted butter and stock.
- Onion
- Releases sweetness and aroma into the braising liquid as it cooks.
The step that matters
Stir in flour until brown. Cooking flour in butter until browned develops nutty flavor and color, and it must be stirred constantly so it does not scorch. Undercooked flour leaves a raw, pasty taste in the gravy.
Swap the onion
How well each one fits the dish's main ingredients (liver, pork, carrot, turnip, parsley, butter, flour):
- Leekfits better
- Parsnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against liver, pork, carrot, turnip, parsley, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
