Well, that was a successfuel (<-- typo but I’ll leave it!!) experiment. UU with half a veggie stock cube, half a teaspoon of marmite, some black pepper, some chilli powder and some of that seaweed you use to make miso soup. Drank it hot out a big mug.
Only trouble is I now want another big mugful! 
I think I definitely prefer going the savoury route so will need think about what I can buy in to flavour it, rather than just seeing what I’ve got in the cuboards.
