Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Scalloped Turnips
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the turnips
Slice the turnips.
Stew the sliced turnips in water with a little butter and salt until tender.
Remove excess liquid and reserve it for the sauce.
Make the sauce
In a separate pan, combine the reserved liquid with flour and the remaining butter to make the sauce.
Assemble and bake
Butter a baking dish.
Layer the sliced turnips, dusting each layer with pepper and some sauce.
Continue layering until all turnips are used.
Top the final layer with grated Parmesan cheese and small flakes of butter.
Bake at 400°F (200°C) until light brown.
Serve in the same dish.

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
- Turnips
- Form the bulk of the dish, becoming tender when stewed and layered.
- Butter
- Adds richness and moisture, and helps the top brown during baking.
- Flour
- Thickens the reserved cooking liquid into a sauce that binds the layers.
- Grated parmesan cheese
- Melts and browns on the top layer, adding savoury flavour and a golden crust.
The step that matters
Remove excess liquid before making the sauce. Excess water dilutes the sauce and keeps it thin, so the layers can turn soggy. Reserving the liquid and thickening it with flour gives a sauce that clings to the turnips.
Swap the turnip
How well each one fits the dish's main ingredients (butter, flour, pepper, parmesan cheese, bread):
- Asparagusfits better
- Spinachfits better
- Tomatofits better
- Turnipthe original
Fit is the average pairing score against butter, flour, pepper, parmesan cheese, bread. 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.
