I made mine with gluten free bread crumbs, and baked them, but feel free to use what you like, have on hand, or have the time and energy for — frozen chicken fingers (yup, the is what mom usually did), homemade fried or baked breaded chicken tenderloins, really even boneless, skinless breasts can be used if you want to keep it lighter, but it doesn't absorb the flavor and help to
thicken the sauce quite as well.
Not exact matches
For this recipe (and
sauces generally) you will want the pulverized flour / starch — I usually buy the one made by Bob's Red Mill (looks like: https://www.amazon.com/Bobs-Red-Mill-Tapioca-Flour/dp/B000WLHOY2)-- it lasts forever and has saved me a bunch of times with
sauces / gravies that aren't
quite thickening up (its effects are instant).
The
sauce, with tomato paste, chicken broth, vinegar, and hoisin
sauce,
thickens up
quite nicely in the wok.
Next time I will do as another suggested and make the
sauce in advance; it took
quite awhile to reduce and
thicken.
My
sauce didn't
thicken up
quite like I'd hoped, but pineapple can be tricky that way.
