Why it works: Leek and turnip 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 ↓
Pot-au-feu
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
In a large pot, place the beef and cover it with water.
Add the chopped vegetables and bouquet garni.
Season with salt and pepper.
Simmer and serve
Bring to a boil, then reduce heat and simmer for 2-3 hours until the meat is tender. Skim off any foam that rises to the surface during cooking.
Serve hot, with the broth and vegetables.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Slow simmering turns the tough cut tender and gives the broth its rich meaty flavor.
- Carrots
- Release sweetness and color into the broth as they cook.
- Onions
- Add savory depth and sweetness to the broth as they soften.
- Leek
- Adds a mild onion-like sweetness and aroma to the broth.
- Turnip
- Contributes a mild, slightly peppery flavor and soft texture to the broth and vegetables.
The step that matters
Skim off the foam. Foam rising during the boil carries denatured proteins and impurities that can cloud the broth and taste bitter. Removing it as it forms keeps the broth clear and clean-tasting.
