thats a really nice mixture you've ordered! if you want to really get the good stuff out of the marshmallow soak them in hot water as long as you can. so over night, pour boiling water over it, and let it sit with a lid on. you can leave it like that and strain it. but to really get the "slip" out of it, i boil it for a few minutes, then i take it off the heat. then i let it to stop bubbling and boil it again. i do this for 15 minutes or so. add more water if it disappears. when its "done" the water should be nice and thick and sticky. its this stickyness that gives you the slip.
hope that has helped.
