Is there any reason why you can't use a latte made with just milk and coffee as a hex? Obviously if it's got syrup, cream etc it'd need synning but otherwise I would think it'd be ok...
Ah, cheers. I'm breastfeeding so get 6 hexs, at least 3 of which have to be hexa, and I do struggle to use them, so a latte would be a good use I think!
