I can readily buy 2000 calories of food that are shelf-stable for under the $9/day price of solent. That are equal in weight (500g), hit a target of 15% protein, are compact in volume... and far more palatable for long durations.
Soylent has going for it that its easy 1-step and always predictable with minimal preperation and packaging. Once I start having to mix or pre-soak, Soylent has no apparent advantage to the system I just highlighted above.
It basically becomes assemblage if not outright cooking. And the need for something like a fridge? Again I think it is capital intensive and sort of against yhe minimalist ethos/usp of soylent.
Do tell, what's your secret?

With that said, i'm super excited for it, and i've been drinking DIY "Soylent" for a few days now, since i'm getting impatient waiting for official soylent, and i couldn't be happier. It's everything i wanted. Once the official stuff gets here, i'll spend even less time preparing, and in theory it will taste better too (mainly less grit).
It's a widely suggested tip, but it's not as if it's a documented instruction step.
in my opinion, to review any experience other than the one derived from exact use of the instructions is rather dishonest.
