Why it works: Parsley and sage match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,445 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Pig's Liver, Baked
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.
Prepare
Soak the pig's liver and cut it into slices less than ½ inch thick.
Boil and mash the potatoes.
Layer and bake
Layer half of the mashed potatoes in a well-buttered mold.
Add a layer of liver slices and bacon slices, then sprinkle with pepper, parsley, onion, and sage.
Repeat the layers, finishing with a layer of mashed potatoes on top.
Pour ½ cup of boiling stock or water over the dish.
Bake in a preheated oven at 350°F (175°C) for 2 hours.
Turn the mold onto a hot dish and brown the top before serving.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig's liver
- Forms the main meat layers, giving a rich, savoury flavour and dense texture.
- Potatoes
- Form the mashed layers that hold moisture and give a soft, starchy body.
- Bacon
- Melts fat into the layers, adding moisture and savoury flavour to the liver.
- Stock or water
- Adds moisture during baking so the layers stay tender rather than drying out.
The step that matters
Pour the boiling stock or water over the dish before baking. Liquid added to the layered dish creates steam in the oven, keeping the liver and potatoes moist while the dense layers cook through over the long bake.
Swap the onion
How well each one fits the dish's main ingredients (liver, potato, pepper, parsley, sage):
- Carrotfits better

- Parsnipfits better
- Onionthe original
Fit is the average pairing score against liver, potato, pepper, parsley, sage. Candidates are from the same food group and used in at least 100 recipes.
