hi there, I love the mix a mousse - its no flavour it just goes into whichever shake you want. you just put a scoop in with shake - give it a mix and then pour in a bowl - leave in the fridge for about 15 minutes - lovely. x
i'd put the scoup of mix a mouse in the packet of your chosen shake and mix a bit. then make sure your water is cold, start whisk and then add the CD shake, keep mixing until fully combined. pop in fridge. leave to set for 5-10 mins. no longer than 15 mins should be fine.
It's great with any flavour you like as a shake really, as long as you get the consitency right. I managed to fluke a perfect one the first time, but had mixed results from there on.
