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 ↓
Creamed Parsnips
Ingredients
Directions
Prepare the parsnips
Boil, scrape, and slice the parsnips crosswise.
Heat the butter in a saucepan, add the parsnips, and shake until coated and hot.
Transfer the parsnips to a deep dish.
Make the sauce and serve
In the same saucepan, add flour to the remaining butter and thin with hot cream.
Boil the sauce once, then pour over the parsnips and serve.

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 bulk of the dish and become soft and sweet when cooked.
- Butter
- Adds fat and richness and helps coat the parsnips.
- Flour
- Thickens the sauce as its starch swells in the hot butter and cream.
- Hot cream
- Supplies liquid and richness, turning the flour mixture into a smooth sauce.
The step that matters
Boil the sauce once. Flour only thickens fully when the starch in the butter and cream mixture reaches a boil and swells. Stopping short can leave the sauce thin and tasting of raw flour.
Swap the parsnip
How well each one fits the dish's main ingredients (butter, flour, cream):
- Leekfits better
- Arrowrootfits better
- Chivefits better
- Parsnipthe original
Fit is the average pairing score against butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
