Just thought I’d pass on some experience and thoughts on using Huel camping, since we used it for a couple of days out over the weekend.
In prep I did some density calculations and concluded that you could fit one three-scoop meal into ~190ml; I rounded this up to 200ml and went to pre-mix powders (I use ⅔ U/U, ⅓ vanilla) and flavour for four meals. Quickly concluded I’d be better off with 250ml volume per meal: a one litre container with four meals in it has enough free space for you to shake and mix the powders really thoroughly, and to store the scoop. So one litre for four meals was convenient for ease of prep.
In practice it worked really well: just staggered down to the stream, filled, mixed, topped up and if we’d had anywhere urgent to go I’d’ve been moving with my breakfast in hand pretty much immediately, while there was quite a lot of ongoing camping stove trauma being suffered by others. I used matcha as flavouring, so the morning’s caffeine hit was taken care of as well.
Two notes on “in practice” — firstly, I needed an extra water container to top up the last 300ml of water; I guess you might be able to just submerge the shaker in the stream, at a pinch. Secondly, the Huel shaker actually did pretty well as a water bottle in between meals. This surprised me: I figured the rubber-free seal wouldn’t be up to keeping water in the bottle, but it seemed to work. Wouldn’t bank on it, but It Worked For Me™.
Future thoughts: I found working with the 1l container fine, but in worse weather conditions it might have gone badly. Next time I might experiment with getting some small plastic bags, mixing all the powders in bulk and then loading one meal into each bag. I note that the Huel shaker itself has an internal capacity of 750ml, so you should be able to fit 3 or even 4 meals in there if you’re using bags and squeeze them in tight. That would have decreased packing volume by a good amount, though I’d worry a bit about the bags’ integrity while out of the shaker when I’m actually using it for a meal.
Obviously there are great advantages to having some warm food or a hot drink; we mixed and matched a bit, but on this basis I’ll definitely be using Huel again.
One final question I have for @TimOfficeHuel — did Huel design their own shaker, or is it just something generic you’ve had branded? If the former, then noting my above comment of 750ml internal volume, I speculate that you could custom-design three odd-shaped plastic containers that would stack inside of it, each containing exactly one three-scoop Huel meal in powdered form. What do you think?
