Why it works: Sweet potato and beans match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 165 recipes. Both carry damascenone, which smells apple, rose. The science ↓
Clear Vegetable Soup
Ingredients
Directions
Make the broth
Place the shin of beef in a large kettle and cover with cold water.
Simmer gently for three hours (can be done the day before).
Strain the broth and remove any fat from the surface.
Return the clear broth to the kettle.
Add the vegetables and serve
Cut the vegetables into uniform pieces.
Add the carrot, turnip, sweet potato, beans, and rice one hour before serving.
Add the potato, peas, corn, and tomato twenty minutes before serving.
Season with salt and pepper to taste and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Simmered for three hours to release flavor and body into the broth.
- Carrot
- Adds sweetness and color, and holds its shape during the longer simmer.
- Sweet potato
- Adds natural sweetness and a soft, starchy body to the soup.
- White potato
- Adds starch that softens and gives the soup a fuller body.
- Rice
- Releases starch into the broth, thickening it slightly as it cooks.
- Tomato
- Adds acidity and brightness that balances the rich beef broth.
The step that matters
Strain and skim the broth before adding vegetables. Removing fat and solids leaves a clear, clean-tasting broth. Skimming fat from the surface prevents a greasy mouthfeel, and adding vegetables to unclarified broth would cloud it.
Swap the peas
How well each one fits the dish's main ingredients (beef, carrot, turnip, sweet potato, potato, corn, beans):
- Chickpeafits better
- Lentilsfits better
- Chestnutfits better
