When making the sauce in this recipe, add the flour and spices to a pan and stir. The flour and spices will be dry. Slowly drizzle your liquid, for example, chicken broth into the flour and whisk continuously until a smooth sauce forms. The sauce will thicken as you heat over medium to low heat. Add wine by whisking into the sauce. An alternate method is to start with a flour slurry. Mix 3 tablespoons of flour with 1/4 cup of water in a sealed, covered container, and shake vigorously. A small amount of additional water can be added if needed. Reshake the container until a smooth liquid. Slowly drizzle the flour slurry into the hot pan and stir with a whisk. The flour will thicken as it heats. Keep your temperature to a medium-low level and don't overcook once the sauce forms and is the consistency you are looking for.
