Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Peas in Turnip Cups
Ingredients
Directions
Prepare the turnips
Pare and shape the turnips into handleless cups, saving the scooped parts for soup.
Boil the turnips in salted water until just tender.
Lift the turnips from the water and pour 1 tablespoon melted butter over the outsides.
Make the peas
In a saucepan, heat the peas.
Add flour moistened in milk and let boil for one minute.
Add ½ teaspoon salt and ½ tablespoon butter, including any liquid that drained from the turnips.
Serve
Place the turnip cups on a platter, fill them with peas, and serve one to each guest.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the edible cups that hold the peas, and their flesh softens when boiled.
- Peas
- Provide the filling, adding bulk and a sweet, mild flavor to the dish.
- Flour
- Thickens the milk into a smooth sauce that coats the peas.
- Milk
- Forms the liquid base of the sauce, adding richness and body.
- Butter
- Adds fat for richness and flavor, both on the turnips and in the sauce.
The step that matters
Add flour moistened in milk and let boil for one minute. Flour must be fully dispersed in liquid before heating, and it needs to boil to cook out its raw starch taste and reach full thickness. Lumps or undercooked flour make the sauce pasty and floury.
Swap the peas
How well each one fits the dish's main ingredients (turnip, butter, milk, flour):
- Almondfits better
- Chestnutfits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against turnip, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
