Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
In a large pot, melt the butter over medium heat.
Add the French beans, onions, turnips, carrots, leek, spinach, celery, and parsley. Fry until softened.

Simmer for 2 hours, then pass the mixture through a sieve.
Stir in a little butter, sugar, and cooked rice.
Serve very hot.
