I do! I like the Chocolate hot and the Choc Mint and Choc Orange. All really yummy! I make it up cold in my blender, then microwave for just under a minute.
I normally fill the mug I'm using with cold water - try and choose a big mug and then blend. I never actually measure - the 227 would do a really thick hot chocolate, though I've done it thinner before and hot and it was still nice.
