This recipe is a copycat version of KFC gravy.
Achieving the characteristic flavor of this gravy hinges on properly developing the roux. Cook the flour and butter for the full 20 minutes, or until it reaches a deep golden hue and emits a distinct toasted aroma; this nutty flavor is key. When incorporating the water and bouillon, whisk vigorously to prevent lumps, ensuring a silky-smooth texture. For an even richer, more authentic taste, consider substituting some or all of the water with drippings from roasted or fried chicken. Adjust black pepper and bouillon quantities to taste after thickening, as sodium levels can vary. A well-cooked onion provides a subtle sweetness that balances the savory notes. Ensure the gravy is brought to a full boil to activate the starch and achieve proper thickness.
