Who can beat a strawberry smoothie? I only use four ingredients – strawberries, 1 ripe banana, milk, and one tablespoon of a liquid sweetener. (I also love adding vanilla but I have just run out of it). To enhance the colour I found a couple tablespoons of grated beetroot deepen the desirable pink colour. (It requires a lot of strawberries to make it bright pink otherwise). I buy strawberries on special, wash and remove the green bits, then chuck them in freezer bags and freeze them for when I need them, otherwise they go off pretty quickly.
