What each ingredient does
- Sea-kale
- Is the vegetable being cooked, so its tenderness depends on cooking time and water heat.
- Melted butter
- Adds fat and richness to the cooked kale as a finishing sauce.
The step that matters
Drain the kale well. Water left on the cooked leaves dilutes the melted butter and makes the dish watery, so thorough draining keeps the butter clinging to the kale.
