Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Calf's Liver
Ingredients
Directions
Prepare
Bring water with a little salt to a boil.
Add the liver and boil for 5 minutes, then drain.
In a bowl, mix sweet oil, bay leaf, thyme, parsley, green onion, salt, and pepper.
Add the liver, cover, and marinate for 4 to 6 hours, turning occasionally.
Roast and serve
Wrap the liver in buttered paper and roast over a fire, basting with oil from the marinade.
Remove the paper a few minutes before done, baste with drippings until cooked, about 35 to 45 minutes.
Serve with gravy or a piquante sauce.

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 protein; boiling then marinating and roasting shape its final texture and flavor.
- Sweet oil
- Carries the herbs and aromatics into the liver and keeps the surface moist while roasting.
- Butter
- Enriches the flavor and adds richness to the wrapping paper and the cooking surface.
The step that matters
Remove the paper before the liver is done. Liver overcooks quickly and turns grainy and dry. Pulling the paper near the end lets the surface brown and be basted with drippings while the interior finishes gently.
Swap the onion
How well each one fits the dish's main ingredients (liver, thyme, parsley, pepper, butter):
- Carrotfits better
- Shallotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against liver, thyme, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
