Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beets
- Provide the earthy sweetness and the main body of the salad.
- Red onions
- Add sharp flavor that softens and sweetens as they cook.
- Green beans
- Add crisp-tender texture and a fresh, green contrast to the beets.
- Olive oil
- Adds fat and richness, carrying flavor across the salad.
- Vinegar
- Adds acidity that brightens the sweet beets and onions.
The step that matters
Cook the onions until tender but still vibrantly colored. Overcooking onions dulls their color and turns them soft and sweet-bitter, while stopping too early leaves them sharp. Cooking gently over medium heat keeps them tender and bright.
Swap the green beans
