Melt the butter in a medium-sized pan over low heat. Whisk in the rice starch. Let bubble until the roux is golden brown.
Add the remaining ingredients in this order: Chicken stock, turkey drippings, aminos, fruit juice, and herbes de Provence.
Raise the heat to medium and bring the gravy to a low boil. Let the gravy simmer and stir frequently until right before it reaches the desired consistency. Take off the heat and let it thicken for 2-3 minutes. Serve warm!
Notes
*Plus more to taste. The color of your gravy can vary each time.
