In blender container, add choice of milk, strawberries and sweetener of choice. Blend on low until berries are starting to get broken down.
Add ice, a little at a time, and process until desired consistency. Should take about a minute or so.
Note: If using the VitaMix, add all ingredients and blend on HIGH for 30-60 sec. Use tamper to push berries and ice into blades; when motor 'growls', it's ready. Recipe was originally formulated for the Model 6300 and to use the "frozen desserts" setting.
