Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow split peas
- Break down during simmering to thicken the soup and give it body.
- Sweet potato
- Breaks down into soft pieces that add body and natural sweetness.
- Onion
- Softens and builds a sweet, savory base for the soup.
- Nonfat yogurt
- Adds cool creaminess and tang as a topping that balances the spices.
The step that matters
Simmer until the peas and potato are very tender. Split peas and potato need a long, gentle simmer to fully soften. Undercooked peas stay grainy and keep the soup from thickening smoothly.
