I have quite a few unsweetened 1 litre long life Almond milk in cartons,don't have to keep them in the Fridge,but I did keep all of mine their - some have gone completely frozen in the Fridge - I defrosted One - a little - for about 1 hour - is a very hot day - so I blended Almond milk ice,had too break it off into small ice bits - the small banana pieces were frozen as well - did have defrosted Almond water from the liquid that came from the Almond milk ice.
Did use 200ml of Lyle's Golden Syrup,the Nutri Ninja Cup has measuring lines on it - I poured the Syrup in - too the 200ml mark in my biggest Nutri Ninja Blender Cup - I may have made it too sweet,but I like it - is a drink that I made up - I know from reading books about Smoothies that it is possible too use Almond Milk.
