Personally this dosen’t work for me as it clumps up as soon as the water touches it.
I found it better to decant Huel into little containers and bring one intowork each day with my beaker.
You can then fill the beaker with water and add the container quickly to the top before shaking.
Coincidentally I added a picture of this to a thread yesterday = this link might work: Results: 1 year on Huel
