Banana Berry Icecream

Reuben requested icecream recently when I was in the middle of a haze of glucose experimenting. I froze at the idea (ha ha, hope you like the pun) of him eating sugar and wondered how I could get around it. Actually no, I didn't. He eats very little sweet food, he's just not in to it (with a few exceptions). He turns his nose up at my baking and tells me his favourite food is broccoli (though I can hardly believe it). So I wasn't afraid of a little icecream.
