Bring everything (excluding persimmons) to a boil in a pot on the stove, then cool the liquid to room temperature. Soak the persimmons in the liquid in the fridge for up to 24 hours.
Remove persimmons and liquid from the fridge and warm up in a pan. Pull the persimmons out of the marinating liquid and place in a bowl. Simmer the liquid until it reduces and thickens, then pour it over the persimmons. Set aside.
For assembly
Place crème fraîche base on plates. Top with persimmons and garnishes.
Notes
Plan a day ahead based on how long you’d like to marinate the persimmons.
