So I have been using Huel for over a year and I am still bugged by this mild annoyance. After shaking (using the original shaker sent with my first order still) there is always a bit of huel that sits in the cap. If ignored it will dribble down the shaker and onto my hand. With the shape/size of the cap though you can’t wipe it away or anything - so I resort to “licking” it out of the cap and always feel a tad foolish trying to make sure there isn’t any left to drip out later or dry/crust up.
I figure this could be a place to share in my trivial annoyance - or perhaps share a solution that you’ve been using Happy Hueling
