We're working on a story at CHOW about different ways to make astronaut ice cream, including easy versions to make at home. Today we had our first experiment, and it was somewhat successful - basically, we made some dehydrated milk foam.
We basically followed the dehydrated milk foam recipe found here: http://www.starchefs.com/chefs/rising...
It consists of heating up milk and glucose (we also added a bit of vanilla), then foaming it with a hand-blender. We took the foam and put it in the dehydrator at 160 degrees for about 4 hours, and then took it out. It came out pretty well, but the foam wasn't very puffy, so it came out more like chips than solid bites. It did melt on the mouth like astronaut ice cream though.
Now we're thinking of some other experiments, and I'm wondering if anyone has any tips. Has anyone ever tried:
1) Dehydrating whipped cream? What does that end up like?
2) Using a different method for the milk to get better foam? We're thinking we might use a whipped cream canister for this.
3) Making dehydrated chocolate mousse, like the recipe in the link. It sounds interesting, but not sure if the texture would be like astronaut ice cream
Any tips would be great! Also, if you have a dehydrator and you like experiments, our first recipe wasn't bad at all. Kind of a fun activity!
