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
Lard the liver in three rows.
Place several strips of salt pork over the top.
In a baking pan, add the sliced carrot, turnip, onion, and salt pork.
Place the liver on top of the vegetables.
Add 1 cup of stock or hot water, 1 teaspoon of coarse sea salt, 4 peppercorns, and a sprig of parsley.
Braise
Cover with another pan and cook in a 350°F (175°C) oven for 2.5 hours, basting often.
Add more stock or water if necessary.
Make the gravy and serve
To make gravy, melt 2 tablespoons of butter in a saucepan.
Stir in 1 tablespoon of flour until brown, then gradually add 1 cup of strained stock from the pan.
Season with more salt and pepper if necessary, and pour 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 meat, becoming tender as it braises slowly in liquid.
- Salt pork
- Melts fat and flavour into the liquid and over the liver as it cooks.
- Butter
- Enriches the gravy and carries flavour when melted with the flour.
- Flour
- Thickens the gravy as it browns in the melted butter.
- Onion
- Adds sweetness and aroma to the braising liquid as it softens.
The step that matters
Keep the liver moist while it braises. Liver is lean and dries out and toughens with long heat. Basting often and topping up the liquid keeps the surface moist and the interior tender, so the liver stays soft rather than firm and grainy.
Swap the onion
How well each one fits the dish's main ingredients (liver, pork, carrot, turnip, parsley, butter, flour):
- Leekfits 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.
