Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover meat
- Forms the bulk and main texture of the hash.
- Onion
- Adds savoury aroma and mild sweetness as it cooks.
- Butter
- Adds fat for richness and helps the surface brown.
The step that matters
Add only a little water. Water turns to steam in the oven, and too much moisture keeps the hash soft instead of letting its surface brown. Add just enough to keep the mixture from drying out.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (meat, onion, butter):
- Garlicfits better
- Thymefits better
- Capersfits about as well
- Parsleythe original
Fit is the average pairing score against meat, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
