My sister is a big hiker/camper. I got her the Ice Cream Ball (like the one sold in the LL Bean catalog) Only I got it at Homegoods for half the price. The idea is to put the ingredients inside the ball, and then you would roll the ball around for I think 30 min, and TADA...you have ice cream. I am going to get the ingredients to go with it. I think she'll love it!
