Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parsnips
- Provide the main body and sweet, earthy flavor of the mash.
- Butter
- Adds richness and a smooth, silky mouthfeel to the mash.
- Cream
- Adds moisture and loosens the mash into a smooth, spoonable texture.
The step that matters
Pound the parsnips while they are still hot and tender. Cooked parsnip starch and fibre break down most easily when warm and soft. Pounding cool or undercooked parsnips leaves lumps and a stringy, uneven texture, so the mash will not be smooth.
Swap the white pepper
How well each one fits the dish's main ingredients (parsnip, butter, cream):
- Nutmegfits better
- Parsleyfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against parsnip, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
