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 ↓
Calps Liver
Ingredients
Directions
Prepare
Bring water with a little salt to a boil.
Add the liver and boil for about 5 minutes, then drain.
Marinate
In a bowl, combine 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 on a spit, basting with oil from the marinade.
Remove the paper a few minutes before done, baste with drippings until cooked, and serve with gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver (in the method)
- Is the main protein; boiling, marinating and roasting shape its final texture and flavour.
- Sweet oil
- Carries the herbs into the liver during marinating and keeps the surface moist while roasting.
- Butter
- Adds richness and flavour to the liver and the gravy.
- Claret wine
- Adds acidity and depth of flavour to the gravy.
- Flour
- Thickens the gravy so it coats the liver.
The step that matters
Remove the paper a few minutes before done. Wrapped meat steams instead of browning. Unwrapping near the end lets the surface brown and dry slightly, while basting with drippings keeps it from drying out. Overcooked liver turns dry and grainy, so timing matters.
Swap the onion
How well each one fits the dish's main ingredients (thyme, parsley, pepper, butter, flour, wine, allspice):
- Shallotfits better
- Carrotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against thyme, parsley, pepper, butter, flour, wine, allspice. Candidates are from the same food group and used in at least 100 recipes.
