Don't freak out over the consistency. It will solidify as you cook. But keep stirring!
After it comes together and has formed a ball, remove from heat and allow to cool. I set mine on waxed paper until it was cool enough to touch, then I gently kneaded it a few times.You need to store this in airtight container (or ziplock bags). I popped mine in the fridge due to the powdered milk content. Anyone have any thoughts on that part??
I'm still deciding how I want to package this for the kids at school. I have a few options and will post after I decide! Enjoy.
