When completely melted, whisk in the flour. Whisk until the flour and butter turn into a smooth paste and look medium blonde in color; about 2 minutes.
Add the minced herbs and continue to whisk.
Slowly pour in stock, whisking the entire time. Continue to whisk until thickened and smooth.
Bring the gravy to a low bubble. As it simmers, it thickens and becomes glossy.
Remove from the heat then stir in the cream.
Taste for seasoning and adjust with salt and black pepper.
