Why it works: Sage and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,388 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Pig’s Liver, Savoury
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.
Prepare
Wash and dry the liver, then cut it into thick slices.
Dice the onions and slice the potatoes.
Assemble
Layer potato at the bottom of a greased pie dish, then add liver slices, sprinkle with onions, and season with salt and pepper.
Repeat layers until all ingredients are used, finishing with a layer of potatoes on top.
Bake and serve
Pour in the water, cover with greased paper, and bake at 300°F (150°C) for about 2 hours.
Remove the paper towards the end to brown the potatoes.
Serve with apple sauce.

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 body of the dish and gives it its rich, savoury flavour.
- Potatoes
- Add bulk and starch, soaking up the cooking liquid and browning on top.
- Onions
- Soften and turn sweeter as they bake, adding aroma and flavour to the layers.
The step that matters
Covering, then uncovering the bake. Liver is easily overcooked, and its proteins toughen and dry out with prolonged heat. Baking covered at a low temperature with added water keeps the layers moist. Removing the paper near the end lets the potatoes brown without drying the liver further.
Swap the apple
How well each one fits the dish's main ingredients (liver, potato, onion, sage, pepper, sauce):
- Limefits better
- Lemonfits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against liver, potato, onion, sage, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
