So based partly off some positive reviews on here I ordered the £4 Huel trial pack.
Gave it a go for lunch today, mixed 100g with 500ml water. Gave it 60 seconds (so 3x the recommended 20 seconds shake) in a shaker, as I hate lumps in shakes and it still came out lumpy. So I then blended it for 30 seconds and consistency wise it was about there. Not pleasant, but doable. Flavourwise I found it probably worse than any protein shake I've tasted. Not horrible, but nothing close to pleasant.
So to try and help I did 2 things recommended to improve the flavour, I added a shot of coffee and put it in the fridge for an hour. It's a tiny bit better, but it really does taste like I'm drinking blended cardboard. I understand why it's like that, but I can't think that this will be ordering any more I don't think.
