Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Steamed Liver
Ingredients
Directions
Prepare the liver
Soak the liver in water or sour milk for 1 hour, changing the water several times to remove toxic blood.
Remove the skin from the liver and tie bacon or suet over it.
Roll the liver in flour and steam in fat for 20 minutes.
Steam and season
Add enough boiling water to half cover the liver.
Flavor with bay leaves, salt, pepper, onions, vinegar, and sugar, then steam for about 1 hour, keeping the saucepan covered.
Serve
Serve with potatoes or an apple and lettuce salad.
Strain the gravy for use the next day.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh liver
- Forms the main body of the dish, cooked gently by steaming until tender.
- Bacon or suet
- Adds fat that bastes the liver and keeps it moist during steaming.
- Flour
- Coats the liver so its surface browns and the juices are held in.
- Onions
- Add sweetness and aroma to the steaming liquid and gravy.
- Vinegar
- Adds acidity that brightens the rich flavor of the liver.
The step that matters
Keeping the saucepan covered while steaming. Covering the pan traps steam so the liver cooks evenly in moist heat. If the liquid boils away or the lid is lifted too often, the liver can dry out and turn tough.
Swap the potato
How well each one fits the dish's main ingredients (liver, flour, pepper, onion, vinegar, sugar):
- Mustardfits better
- Capsicumfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against liver, flour, pepper, onion, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
