I used to make 'instant icecream' for my children.
Soft fruit, including strawberries, were cut into pieces and kept in the freezer. When 'icecream' was needed, I put frozen fruit into the Magimix with plain yoghurt and whizzed. Hey presto, icecream!!
It was always used when it was made, but someone might like to try freezing it and report back.
Admittedly, this is not a cordon bleu recipe, but it always hit the spot on a hot day.
