Boil a pot of water that will fit your beans. Add 2 tsp salt to the water. Place the green beans in the water and cook for 5 minutes. When they are tender, strain them from the hot water and add the beans to a bowl of icy water to quickly stop them cooking further. Place in a serving bowl.
Stir together the marmalade, salt, soy sauce, and sriracha (adjust to desired spiciness)
Add the sauce to the cooked beans and toss to coat. Serve hot
