Q&A
1. How Long can we keep the sauce for future use?
Should you fill the sterilized jar, seal and let cool in room temperature before keeping in fridge, you may keep for 1 month. Alternatively, you may freeze it immediately for extended storage of 2 months. Once thaw and open, please consume within a week.
2. How to thicken the sauce? Add cornflour?
Depends on applications, you may do reduction or thickening.
For thickening, please use starch solution, starch to water ratio 1:1
3. May I use chinese wine to replace cooking sake ?
I recommend the use of cooking sake as that will result the beautiful Japanese teriyaki fragrance. You may still be able to execute the recipe by replacing the cooking sake with chinese wine, and by replacing Japanese soy sauce with Chinese soy sauce but that will not result the same flavour as suggested by this recipe.
