Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green french beans
- Form the bulk of the dish and give it a tender, slightly crisp bite.
- Tarragon
- Adds a distinctive, slightly anise-like aroma that brightens the beans.
- Chervil
- Adds a delicate, mild herbal aroma that suits the tender beans.
- Chopped chives
- Add a mild onion-like freshness and aroma to the beans.
The step that matters
Boil the beans until just tender. Beans cook through as their starches soften, and overcooking turns them soft and dull green. Stopping at tender keeps the bright colour and a pleasant bite once the herbs are added.
Swap the beans
How well each one fits the dish's main ingredients (tarragon, chervil, chive):
- Lentilsfits better
- Chestnutfits better
