Once the soup has cooked in the crockpot on high for 4 hours, you will take the chicken breast out of the crockpot and shred. Then put the chicken back into the crockpot.
At that point, in frying pan you will add 1/4 butter to the pan, on medium heat you will let it melt, then add in 1/2 cup of the brown rice flour. Mix the flour into the butter and let cook for 1 minute.
