Magia, I make my own, from scratch, but eye-ball it, no measuring, so will try to estimate.
1/4 cup soy sauce
1 tsp honey (or to taste) (if you prefer, brown sugar)
2 Tbs orange juice, or to taste
1 tsp mirin
1 tsp minced fresh ginger
1 Tsp minced fresh garlic
Taste and adjust seasonings. I sometimes add a couple drops of dark sesame oil, or fish sauce, or hoison sauce, but this makes it a whole new flavor.
For another spin, reverse the amounts of soy sauce and orange juice.
I just use a whole large garlic clove, and about a 1/2+ slice of the ginger root, and I usually just pour the ingredients in and taste and adjust. These are estmates.
