This make ahead Japanese style marinade and teriyaki sauce is handy to have on hand when you need a little bit for marinating raw ingredients or glazing for a finishing touch.
Whisk all the ingredients together in a small sauce pan and heat on medium heat until boiling.
When the sauce starts to boil, lower the heat to medium low so that it simmers. Allow the sauce to simmer for 10 minutes and stir occasionally. The sauce is ready when it thickens a bit and looks syrupy.
Set aside to cool down before using as a marinade. Refrigerate and use within 3-4 days or freeze.*
*I use dried and ground garlic in this recipe and keep any unused amounts of sauce in my refrigerator up to 1 week. But if you decide to use fresh garlic (or any fresh ingredients), it's important to use or freeze within 3-4 days.
