Why it works: Thyme and sage match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,485 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Liver Hash
Ingredients
Directions
Make the hash
Run the leftover liver and bacon through a meat chopper or chop finely by hand.
In a saucepan, melt the butter over medium heat, then stir in the flour and cook until well combined.
Slowly add the milk while stirring continuously until the sauce thickens.
Season the sauce with salt, pepper, thyme, sage, and bay leaf if using.
Add the chopped liver and bacon to the sauce and mix well.
Serve
Serve the hash on slices of toast, topped with a poached egg if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover liver
- Provides the main meaty body and rich flavor of the hash.
- Leftover bacon
- Adds smoky, salty fat that flavors the sauce and hash.
- Butter
- Fat that carries the flour and gives the sauce a rich, smooth base.
- Flour
- Thickens the milk into a sauce when cooked with the butter.
- Milk
- Forms the creamy liquid that the flour thickens into a sauce.
The step that matters
Slowly add the milk while stirring continuously. Adding milk gradually while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly without lumps.
Swap the thyme
The recipe marks thyme as optional. How well each one fits the dish's main ingredients (liver, butter, flour, milk, pepper, sage, egg):
- Nutmegfits about as well
- Parsleyfits about as well
- Thymethe original
- Marjoramfits about as well
Fit is the average pairing score against liver, butter, flour, milk, pepper, sage, egg. Candidates are from the same food group and used in at least 100 recipes.
