I understand that to many (not all, but some), Soylent 1.4 has not been the ideal drinking experience. The texture and flavor seem to be chief among the criticisms, and I also was a little put off: not enough to unsubscribe or even slow my consumption, but enough that Soylent became slightly more of a chore than it was before. However I recently (and accidentally) came across a couple easy things to do that dramatically improved 1.4 in my eyes (or, mouth, rather).
1 - If you can help it, don’t make a pitcher in the evening and let it sit in the fridge overnight before consuming. Make it right before you plan to consume it. The texture is much closer to 1.3 at that point (a little frothy, but not unpleasantly so), and the sharp/briny aftertaste was nowhere to be found. Obviously it won’t work for everyone logistics-wise. I usually just have one glass of Soylent like this, and the rest of the day it’s chilled, but if it warms it does seem to feel better in the mouth. I haven’t tried it via stirring powder into a single serving, so I don’t know if stirring vs shaking works better or worse.
2 - Add fiber. I added a tablespoon of psyllium husk powder to the 2 liter pitcher (mostly because my BM had become a bit more labored than normal, so I wanted to bring my fiber consumption up nearer the recommended level), and I found that the texture that seemed to me like raw egg whites went back to a much more tolerable smoothness. This effect was much less pronounced however, so it’s possible that I’m just getting used to it and this is just a placebo effect.
I know this won’t be ideal for everyone, but I hope it might help someone.
