What each ingredient does
- Leeks
- Are the main vegetable, becoming soft and mild when cooked until tender.
- Butter
- Adds richness and a smooth, savory coating to the cooked leeks.
The step that matters
Cook until tender. Leeks need enough time in boiling water to soften fully, since the thick layers stay firm and fibrous if undercooked. Checking for tenderness with a knife or fork ensures an even texture throughout.
