OK so to prove I am going to make my own Teriyaki Sauce next time...
There seems to be a bunch of different recipes !!! They all seem to include Miran, Soya sauce and brown sugar... any other tips ? I might play around with a few ideas... some have ginger is, some dont... same with garlic...
And yes I know Wasabi doesn't go in... but thinking of doing something for the Wasabi as well... maybe some nice Prawn/Sushi Rolls...
