What each ingredient does
- Sea-kale
- Is the vegetable being cooked, so its tender texture is the main result of the dish.
- Butter
- Adds richness and a silky mouthfeel when melted over the drained kale.
The step that matters
Drain the sea-kale well. Water left clinging to cooked leaves dilutes the melted butter and makes the dish watery, so draining thoroughly keeps the butter coating the kale.
