I based this on a recipe I found online, but tweaked it a bit to serve my purposes. I've included a proprotional recipe as well as one that uses absolute measurments. I like the proportional/ratio-based one because it's easy to scale for any amount of chicken. But if you prefer just having a set list of measurements, that is also included below.
