Why it works: Allspice and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Hashed Liver
Ingredients
Directions
Prepare
Boil the liver until tender.
Chop the hard boiled eggs: mash the yolks smooth and chop the whites finely.
Make the gravy
Combine the chopped eggs with the liver in a pot with enough boiling water to make gravy.
Bring to a boil over medium heat.
In a separate bowl, rub the flour into the butter until well combined.
Stir the butter mixture into the liver mixture.
Season with salt, black pepper, cayenne pepper, allspice, and cloves to taste.
Add wine if desired for extra flavor.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Provides the main body and rich flavor of the dish.
- Hard boiled eggs
- Mashed yolks and chopped whites thicken the gravy and add texture.
- Butter
- Adds fat and richness, carrying flavor through the gravy.
- Flour
- Rubbed into the butter, it thickens the gravy as it cooks.
The step that matters
Stirring the butter and flour into the liver mixture. Flour rubbed into butter must be fully combined and stirred in gently so it disperses without lumps. Keeping the mixture at a boil while stirring lets the starch swell evenly and thicken the gravy smoothly.
Swap the allspice
How well each one fits the dish's main ingredients (liver, egg, butter, flour, pepper, clove, wine):
- Nutmegfits better
- Cinnamonfits about as well
- Thymefits about as well
- Allspicethe original
Fit is the average pairing score against liver, egg, butter, flour, pepper, clove, wine. Candidates are from the same food group and used in at least 100 recipes.
