I’ve only consumed 4 bags worth, but they’ve come from probably 3 different boxes because I’ve been giving so much away to family, friends, and co-workers. The only thing I’ve noticed is that it’s more delicious now than when I started and seems less gritty overall. I attributed both of these changes to just “getting used to it”.
The copacker that actually makes the Soylent (RFI) has been doing what they do for quite some time. I think the chances that you got a box of incorrectly mixed Soylent are probably slim to none. If you have other boxes, I guess you could crack one open and try a bag to see if it’s any different.
Does anyone with any culinary experience know how to make it less sweet, short of diluting it with more water? I’d actually like to know for myself too, because I’d love to try making some Soylent pasta but I wouldn’t want it to be sweet.
