Got this recipe from a guy friend's Mom that I knew in High School.
eagle brand sweetened condensed milk
butter or margarine
3Okay when caramel mixture is al mixed and melted. Drop Mashmallows one at a time into caramel mixture and coat it, then with tongs pick that marshmallow up and drop it into the rice krispies, roll with spoons to coat. I use big tupperware bowls to store these in. Good from the Refrigerator or room temperture.
