I made this little concoction with my youngest son last night. My blender is a Vita-Mix but any high powered blender should work. (Actually, any blender with an ice chopping function should work but I'm not certain how the final texture will be. I always managed to burn out the motors on regular blenders making concoctions like this one.)
Place 3 dried unsweetened, unsulphured pineapple rings and one pitted date in a blender. Pour in 1 cup of boiling water and let the pineapple rings and date soak until the water has cooled. Blend to puree the date and pineapple rings.
Add four frozen bananas and 3 cups vanilla soymilk. Blend until combined. It should have a slushy consistency. If its too watery you can drink it like a smoothie or add some ice and blend a bit more to thicken.
Its reminiscent of a Pina Colada. Enjoy!
