As soon as I opened the bag, it smelled like yellow cake mix. Not a bad smell by any means, I was just surprised at the similarity.
As several people have suggested, I mixed it with just filtered water and left it in the fridge for a few hours. I tried a single cup (mixing two teaspoons of oil in per cup of Soylent) and the texture seemed a bit rough even after mixing in some extra water and Monin green mint syrup (though the latter did help with the flavor). I added some extra water to the pitcher and let both the cup and pitcher sit overnight and the texture was much improved, though it still leaves behind a grainy mouthfeel.
My plan is to “drink” a cup at a time, mixing a bit of oil in each time, and only refilling my cup when I’m hungry for more. This way the oil has a chance to properly mix with the drink instead of separating in the pitcher. I definitely prefer it cold.
I’m thinking I may need a second pitcher though… especially if the first one is almost empty and I need to make a mixture for the next day. I can see this lasting me two days at a time with the occasional non-Soylent snack to break up the monotony. I’m trying to lose weight so I won’t be eating the full 2000 calories each day.
