I made this, this afternoon, for my daughters... and we used three nectarines, some store-bought vanilla ice-cream, and A2 full cream milk... as per the recipe... but we didn't have the straws for serving.
Despite the fact that my children were less than appreciative of the nectarines... (mad, I know!)... they loved this!!! As did I!!!
However, upon reflection, we would reduce the sugar - I found it very sweet, and was agreed with by the wee ones - but they still liked it! I think the purchased ice-cream was very sweet!
It's more liquid than what I would say a smoothie is, but it was lovely.
Give it a go!
