I have had this little recipe for years...but I think only my 2 oldest ever remember doing it before. It is very fun for kids of all ages and very simple.
Here's what you need:
Milk (at least 2%, whole works best!)
You'll also need:
Quart size ziploc
Gallon size ziploc
Fill the gallon size half way with ice and add 6 Tbsp. of salt.
Put 1/2 cup milk, 1 Tbsp sugar and 1/2 tsp of vanilla into a quart size bag. Seal bag. Place in gallon size bag.
Seal and shake for 5-7 minutes. It will become VERY cold. My girls like to have oven mitts on! ; ) Carefully take the small bag out and rinse off with COLD water. You need to rinse off all the salt so that it won't ruin the flavor of your ice cream! Also, make sure none of your bags have holes, because the salt taste will go everywhere!
It turns out more like an "ice-milk", but it is a fun thing for the kids to do and it is still a yummy sweet treat. We had ours tonight on brownies with chocolate syrup! Yum... Not as yummy as Dreyer's (I admit)...but it worked in a pinch!
