I've had a couple Joylent "meals" so far.
First one was weak. I don't think I put in enough powder. Barely any chocolate flavour but still had a bit of the Weetabix dregs texture.
Second meal last night was much better. More pronounced flavour. I think I added more powder and gave it a good mix with a hand blender.
Third meal will be consumed for lunch today. I actually measured it out. One bag contains 515-520 grams of powder. I went with the high end and split into three which gives just over 173g of powder in the mixer bottle. Whisked that up and topped up to 600ml with water. Took a couple of sips and it has improved again.
