Season at the end. Breakfast sausage brands range from mild to very salty and the gravy reduces as it simmers, so add the salt in the last two minutes.
Thickness: the gravy thickens off the heat and much more in the fridge, so pull it a shade looser than you want it on the plate.
Storage: keeps 4 days in an airtight container. Reheat over low heat with a splash of milk, whisking, and never at a hard boil.
Freezing: up to 3 months. Thaw overnight in the fridge and whisk hard over low heat if it separates. Freeze the gravy and the biscuits separately.
Substitutions: hot sausage for more heat, turkey sausage plus 2 extra tablespoons of butter for a leaner pan, or a cornstarch slurry in place of the roux for a gluten-free version. Nutrition values are an estimate.
