Sweetened Condensed Milk

In a blender or with a mixer (blender is best, but use whatever):
1/4 margarine
1/2 c boiling water

With blender on, slowly add
1/2 c sugar
1 1/2 c powdered milk (don't know if you can get that-don't know what to tell you if you cant- prolly have to send it)

let set in fridge for 2-3 hours before using
