Snap Beans
Ingredients
Directions
Prepare
Gather young snap beans, snap off the stalks, and remove the strings without breaking them.
Cook
Bring a pot of water to a boil, add a little coarse sea salt, and boil the beans for about 15 minutes.
For old beans, cut them, add a bit of saleratus to the boiling water, and boil rapidly.
Drain the beans in a colander.
Serve
Place the beans in a dish and add pieces of butter or pour melted butter over them, or serve with brown gravy.

What each ingredient does
- Young snap beans
- Provide the main vegetable; their tender flesh cooks soft while the strings are removed beforehand.
- Butter
- Adds fat and richness, coating the beans and carrying flavor.
- Saleratus
- Raises the water's alkalinity, helping older, tougher beans soften faster during boiling.
The step that matters
Removing the strings without breaking the beans. Strings are tough fibers along the pod seam. Pulling them cleanly keeps the pod intact, so it cooks evenly and doesn't release juices into the water.
