In a large pot, combine the chicken broth, chicken bouillon powder, ground ginger, turmeric, salt, and a dash of white pepper. Whisk everything together until the powders dissolve then heat on medium-high until liquid comes to a gentle boil. Once it reaches a boil, reduce the heat to medium-low and slowly pour in the cornstarch slurry while stirring continuously until the broth slightly thickens, about 1-2 minutes.
