String Beans, English Style
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Prepare the string beans as directed in the previous recipe.
Bring a pot of water to a boil and add a pinch of coarse sea salt.
Cook and serve
Add the beans to the boiling water and cook until tender, about 5-10 minutes.
Do not cover the pot while cooking to prevent discoloration.
Drain the beans in a colander.
Serve with a piece of butter in the center and another piece on top.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- String beans
- Cooked until tender, they become the main body of the dish.
- Butter
- Melts over the hot beans, adding richness and a silky coating of fat.
The step that matters
Leaving the pot uncovered while the beans cook. Keeping the lid off lets volatile acids escape, which helps the beans stay bright green instead of turning dull olive.
