Why it works: Turnip and mustard match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 290 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Stewed Turnips with Onions
Ingredients
Directions
Prepare
Pare the turnips and cut them into four or six pieces, trimming the edges.
Peel the onions and place them in a saucepan with the turnips.
Cook
Add enough water or broth to cover the vegetables, along with the butter and salt.
Cover the saucepan and cook until the turnips are tender.
Drain off the broth and transfer the turnips and onions to a deep vegetable dish.
Finish and serve
In a separate bowl, mix the butter sauce with mustard flour and nutmeg.
Pour the sauce over the turnips before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the main body of the dish and soften into a tender, mild vegetable.
- White onions
- Add mild sweetness and aroma as they cook in the broth.
- Butter
- Adds richness and fat, carrying flavour into the sauce.
- Mustard flour
- Adds a sharp, pungent bite that balances the sweet, mild vegetables.
The step that matters
Cover and cook until tender. Cooking covered in a measured amount of liquid keeps the turnips from drying out while they soften. Cooking too briefly leaves them firm, and too long makes them mushy.
Swap the onion
How well each one fits the dish's main ingredients (turnip, butter, mustard, flour, nutmeg):
