Cook the turkey liver in boiling water until it is slightly pink inside. Dice it into small bits and set aside.
Bring the broth and unflavored gelatin to a boil in a small pot over medium-high heat, then reduce heat and simmer for 6 minutes. Remove from heat and let cool for two minutes.
In a separate bowl, add roughly 1/4 cup of the broth mixture to the two egg yolks, beating continuously with a whisk. Pour the egg mixture back into the broth and continue whisking until combined.
Add minced turkey liver and butter. Stir to combine.
