Why it works: Parsnip and flour match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 669 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fricassee of Parsnips
Ingredients
Directions
Prepare the parsnips
Boil the parsnips until tender.
Scrape and mash them into a stew pan.
Make the fricassee
Add cream, butter, pepper, and salt to the mashed parsnips.
In a separate pan, simmer the parsnips cut lengthwise in a white sauce made of broth, mace, cream, butter, flour, pepper, and salt.
Serve warm.

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
- Parsnips
- Form the main body of the dish, providing starch, sweetness and a soft, mashed texture.
- Cream
- Adds richness and moisture, giving the sauce a smooth, silky body.
- Butter
- Adds fat for richness and a smooth mouthfeel in the sauce.
- Flour
- Thickens the white sauce so it coats the parsnips instead of running thin.
The step that matters
Thickening the white sauce. Flour must be cooked briefly in butter before liquid is added, and the sauce simmered gently while stirring. This cooks out the raw starch taste and lets the starch swell evenly, so the sauce thickens smoothly without lumps.
Swap the mace
How well each one fits the dish's main ingredients (parsnip, cream, butter, pepper, flour):
- Nutmegfits better
- Parsleyfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against parsnip, cream, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
