Disaster!
I have only a little of this wonderful soy sauce left.
I will go to the Darwin Oriental emporium, otherwise known as 'the shop with the smiling chinaman', to see if I can find a suitable replacement. My beautiful girl bought me an extra 500ml of this gorgeous, light brown, delicious sauce before I left Japan earlier this year. But I did not have enough space and I did not bring it.

What a fool I was.

Kikoman black soy is just not a good substitute. I hope Mr Happy can help me.
