I found this on the following Facebook page: http://www.facebook.com/IdealProteinLohja
1 IP drink packet (for example, chocolate drink packet for chocolate ice cream)
½ TSP of vanilla extract
1 packet of sweetener (Truvia, Splenda, etc)
1 cup of water
½ cup of course salt
(Plus a large (gallon) and small (sandwich) sealable ziplock bag.
1. Put 1 cup of water into IP shaker – add in vanilla and sweetener – then the IP drink packet and shake until well blended. Pour mixture into small sandwich plastic bag. SEAL TIGHT.
2. Take a gallon sized plastic bag and fill up half way with ice cubes. Pour ½ cup of salt into the bag. Place the sealed sandwich bag with the drink mixture inside the ice cube bag. MAKE SURE BOTH BAGS ARE SEALED TIGHT.
3. Now here come the little arm workout! Shake, shake, shake for 8 minutes. I usually stop at around 5 minutes and check to see the progress. At about 5 minutes the mixture should be partially frozen – kind of looking like a slushy. (Try pot holders while shaking the bag because it’s cold to hold onto!)
4. At 8 minutes you are going to have a hard bag of ‘ice cream’! Take out of the salty ice bag and very quickly rinse the bag off under cold water.
Note: Kat says that one time when she made this – some of the salt rubbed off the bag and got into the bowl – and took a bite and was like WHOA salty ice cream. So just rinse off the bag quickly to avoid that.
