Why not getting U&U and add ingredients yourself (as many do with fruits) to make it savoury?
Note that I’m not against them adding what you’re asking, just suggesting solutions for you for the time being when this is not a thing
It’s a nice idea, adding this and that to customize it, and I can imagine there’s fun to be had, but I’d be reluctant to start tinkering. The big sell is that it’s ready-to-go right out of the bag and I’d worry about how any flavour additions would skew the balance of nutrients. Plus I’m lazy.
Understandable that cold savoury liquids might be an acquired taste, but it’d be cool (or hot!) if Huel soup was ever a thing. Assuming heat doesn’t degrade the nutrients, but I guess this issue must’ve been dealt with for H&S already.
Incidentally, I took a look at the Thai Green Curry recipe to see when the Huel gets added, ie to see how much heat it’d be subjected to during cooking:
** Finely chop the onion and fry in a large saucepan.*
** Once soft, add the crushed garlic and fry for a further minute or 2 until golden.*
** Add the peas, spinach, thai green curry paste, coconut milk and water and bring to a gentle simmer for about 5 minutes until cooked.*
** Using a hand blender, blend until smooth and season with salt and pepper to taste.*
If the company begins with F, I’ve tried it and sadly it’s rough IMO. I think for cold savoury the texture needs to be very smooth. Sweet stuff can be a little gritty or starchy, but when its savoury and cold it starts to feel weird. So maybe cold savoury would be good as RTD.
Soups however are a great idea, you could sell it in big bags or sachets, cupasoup style. You could get really creative with flavours if they were designed as soups, and they’d also be excellent for people who are trying to gain weight as you could just make a bowl of Huel soup to slurp at alongside a regular meal so you’re basically getting huge amounts of calories without having to do a meal and then afterwards a shake.
