Fill a gallon ziploc bag one-third of the way with ice and 1 cup ice cream salt.
Put 1 cup of ice cream mixture in a quart ziploc, seal it and put it in the gallon bag.
With a towel or gloves, knead it, having the small bag in contact with the ice mixture as much as possible, until it thickens, about 10 minutes, let it sit another 5 minutes to harden, and voila! Ice Cream.
My campground neighbors and I did the experiment this evening and the results were truly excellent. Now I can make 1 single serving of good ice cream at a time, or enough for a group and have them knead their own - it's fun.
Here's the recipe I used:
VANILLA ICE CREAM
1 C milk
1 heaping Tbsp STEVIA
1/8 tsp salt
3 beaten eggs
Cook (stirring) the mixture in top of double boiler until you see bubbles start to form around the edge, and the mixture begins to thicken slightly and coat the spoon.
Let it cool to room temperature.
1 Tbsp vanilla
2 C half-and-half
Put 1 cup of the mixture in each quart bag and proceed with the instructions above.
Next time I'll add berries, and start trying other flavors. But I'm really excited: I now have a good tasting good textured ice cream - which also passed muster from my neighbors who DO eat regular sugar. To quote: "It tastes like Real Ice Cream". Can't beat that!
