Banana and Cranberry Smoothie

I usually have a banana and raspberry smoothie but this morning we had run out of frozen raspberries so I had to improvise with the other frozen fruit to hand. I thought cherries might be too big to work properly, and didn't fancy the mixed summer berries so decided to risk cranberries. It worked, and was very nice, though not as smooth in texture as the usual mixture.

For one large serving you need:
1 ripe banana
1/2 cup frozen cranberries (using frozen ones helps to thicken up the smoothie)
about 200ml soya milk (I never measure it but do it by eye)
1 tsp agarve nectar

Lob everything into a blender and blitz until smooth. Add some more milk until the consistency is right and add more nectar if it's too sharp. Feel virtuous as you sip it.
