sorry about that. Its definitely half a cup. My sons first bday today so only just saw your message.
I weighed them as I was putting them into the thermomix, ie after they were pitted and soaked. However that still sounds a lot more than your weight so sorry if its wrong, I will check again next time. it was a waste of time probably putting a weight on it in this case, I was just trying to do the proper thing but in this case has made it more confusing. I think I will just change it to half a cup as the soaking needs to be done in advance anyway.
It will be interesting to see what you think. I also mixed in some finely diced strawberries at the end, just by hand with the spatula before serving. It makes it a bit more "adult" ;-0
