How much candied ginger in the recipe for Whole Wheat Ginger Zucchini Bread, posted May 15, 2018?

I make a similar loaf call "3-ginger gingerbread" (old recipe from New London Inn in NH), which uses 2 3/4 cup flour (compared to the 2c in the WW ginger zucchini bread from a292).
Thus, use about 2/3 of my measurements.
Fresh ginger: 1 tbsp reduces to 2 tsp
Crystallized ginger: 1/2 cup reduced to about 5-6 tbsp
Powdered ginger: 1 tsp reduces to about 2/3 tsp
