I have tried to find the equivalent ponzu salad dressing from Tokyo mart in Northbridge, but without much success.
Last time I got takeaway from Sushisuma, I got extra salad dressing, which I promptly decanted into a spare bottle.
Just had my first homemade salad, but with the leftover kaiso salad dressing. The cabbage isn't sliced as finely (I don't have a mandolin), and I have no seaweed (subsitituted with coriander, parsley and snow peas), but YUM. oh! and I forgot the mayo! Next time.
