Classic Parsley Sauce with Never Not Eating Sumac S&P

The Stuff:

• 3 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1 cup whole milk (see below)
• 1/2 cup heavy cream
• 1 tablespoon Never Not Eating Sumac S&P
• 3/4 to 1 cup minced parsley

The Method:

1. Heat the butter in a small pot over medium heat. When it's melted and hot, stir in the flour and cook, stirring often, until it turns ivory color, about 5 minutes.
2. Stir in the heavy cream — the mixture will seize up, but keep stirring — then the milk. One cup should get you the consistency you want, which is a thin gravy. Bring this to the steaming point or a very low simmer, but don't let it boil. Stir well. 
3. Mix in the  Never Not Eating Sumac S&P and parsley.
