talk about easy. haven't tried it yet but it sounds great.
further down it says to use a smaller coffee can and a larger can. I think that would be great. Spend no money on an ice cream maker. why bother when you can do it with plastic bags or cans.

This recipe is enough for one. double for bigger portion. (I think this would be a fun little project to try in summer time. fresh ice cream without an ice cream maker)




1/2 cup milk
1/2 teaspoon vanilla
1 tablespoon sugar
4 cups crushed ice
4 tablespoons salt
2 quart size Zip-loc bags
1 gallon size Zip-loc freezer bag
a hand towel or gloves to keep fingers from freezing as well!

Mix the milk, vanilla and sugar together in one of the quart size bags. Seal tightly, allowing as little air to remain in the bag as possible. Too much air left inside may force the bag open during shaking. Place this bag inside the other quart size bag, again leaving as little air inside as possible and sealing well. By double-bagging, the risk of salt and ice leaking into the ice cream is minimized. Put the two bags inside the gallon size bag and fill the bag with ice, then sprinkle salt on top. Again let all the air escape and seal the bag. Wrap the bag in the towel or put your gloves on, and shake and massage the bag, making sure the ice surrounds the cream mixture. Five to eight minutes is adequate time for the mixture to freeze into ice cream.

Tips
Freezer bags work best because they are thicker and less likely to develop small holes, allowing the bags to leak. You can get away with using regular Zip-loc bags for the smaller quart sizes, because you are double-bagging. Especially if you plan to do this indoors, we strongly recommend using gallon size freezer bags.

Coffee Can Ice Cream
An alternative to the baggie method is to use coffee cans. The recipe is the same, and may be doubled or tripled because the coffee can can hold more liquid than the baggies. Put the mixture in a standard size coffee can and seal with the plastic lid, then place that can inside a larger economy size can. Pack the large can with ice and salt, and seal with the lid. Roll the can back and forth on the ground (outside the condensation will drip) until the ice cream is set. The time required to set the mixture will vary depending on the number of servings in the can.

What does the salt do?
Just like we use salt on icy roads in the winter, salt mixed with ice in this case also causes the ice to melt. When salt comes into contact with ice, the freezing point of the ice is lowered. Water will normally freeze at 32 degrees F. A 10% salt solution freezes at 20 degrees F, and a 20% solution freezes at 2 degrees F. By lowering the temperature at which ice is frozen, we are able to create an environment in which the milk mixture can freeze at a temperature below 32 degrees F into ice cream.

Our kindergarten classes used to do this every year with the coffee cans, rolling them around on the front lawn - great fun!

We used to do the same thing, KnittyGritty! (And welcome to Sufficient Self!)

Lots of fun!

Last year, I was in Dick's Sporting Goods. They had some type of ball that you put all the ingredients in and then played w/the ball until the ice cream was made. I was going to buy them for my kids for Christmas, but couldn't find them again. :(
