Hi @Angie8m I would suggest a shaker is by far the easiest way to mix the huel when you’re out and about.
If you email firstname.lastname@example.org they will send you a shaker and T-shirt out if you are a new customer even if you forgot to add it with your order - they are nice like that
In the meantime, probably the easiest way is to use a hand blender to mix it in a large bowl or pan, then pour into a suitable bottle and refrigerate it. Take it with you to work in a cool bag with an ice pack and it’ll stay fresh for a good half day.
Or you could buy a shaker from pretty much any supermarket or bargain store. It’s always handy to have two, so it’s not like you’d be wasting your money while waiting for the Huel one to arrive.
Hopefully you will get your shaker soon
