Okay, okay, here it is! Here's the recipe for shoyu chicken just like you'd find at Local Boyz.
1 C water
1 C soy sauce (I use a little less of the sodium-free Kikkoman)
1 C lightly packed brown sugar (give or take; I'm a giver)
1 tsp ginger (the granulated stuff works just fine)
1 tsp garlic (powdered, again, cheap and easy; don't substitute with garlic salt!)
splash of vinegar (maybe a tablespoon? leave it out if you don't have any)
4-6 whole chicken breasts or thighs or mix-and-match pieces--they'll fall apart on their own
Throw it all in a crock pot, give it a quick stir, set on high for four hours (low for six hours), and walk away. The recipe is perfect for starting on your lunch hour if you can run home--and then it's done when you get home after work! When there is a half-hour remaining on the timer, set your rice to cook. I make 3 cups of white rice in a rice cooker so there is plenty for two people plus leftovers.
This dish will reheat fabulously, so go ahead and make a bunch at once. Increase the ingredients to make more. My average-sized crock pot could easily handle a double batch. I'm not sure it's possible to cook this in a crock pot and make less than my recipe... though you could try it on the stovetop in a pot simmering on low for an hour or two. Use half the ingredients for two small chicken breasts. The stovetop method is the fastest, but the texture of 'fally-aparty' meat won't be the same.
As previously noted, I've accidentally thrown in pork cutlets with the chicken, and that was delicious too. Even steak might work. All of my meat gets trimmed insanely well, so there are no weird pieces like I've sometimes found at the restaurant--another bonus of home-cooked food.
Note on frozen meat: I've always been told never to put frozen meat into a crock pot. The meat apparently will stay in the "danger zone" too long. If you remember to defrost your meat before you put it in the crock pot, great! I forget often. I have thrown frozen meat into cold liquid and left it for six hours multiple times and not been sick. Maybe don't make a habit out of it.
DISCLAIMER: I am not affiliated with the Corvallis establishment Local Boyz. I have never been anything other than an occasional patron there. This recipe is as close to tasting like their shoyu chicken as I can approximate and was achieved through trial and error on my own part.
