Remove the stems, by snapping them off with your fingers (see video)
OR with a paring knife which allows you to cut several at a time. You may trim off the opposite side to match, or not, I like them natural
Wash the beans in cold water
We’re gonna cook the beans in boiling water, we need a pot with a tight fitting lid… Fill it up about half way water and bring to a boil. Add a little table salt (show it in my hand)
Add the green beans. Cook for about 4-5 minutes until they turn bright green and soften a bit, be sure they still retain some snap. Strain the beans and serve with butter and season with salt and pepper
The down side of boiling vegetables is that they lose some of their flavor and nutrients. I find it better to steam vegetables when possible, see broccoli or cauliflower recipe for technique.
