I chanced upon an organic one, paste type (not powdered) in NHF inside Tesco Paradigm Mall.
So I bought a tub. I have been using it for my seasoning and hence hardly any drop of salt use in my dishes for almost 3-4 months? I have made porridge, cantonese gong fu chow, salad and stir fries.
I dont need to use a lot and found a way to store it.
