Brown the Bird: In a pot, heat clarified butter over medium heat. Pan-fry the Cornish hen until golden on all sides, then remove and set aside.
Sauté the Aromatics: Add onion and garlic to the pot and cook until soft and translucent.
Build the Stew: Return the bird to the pot with sliced leeks and water. Simmer for about 10 minutes.
Add the Milk: Pour in milk and stir in salt. Let simmer until the flavors meld.
Thicken the Broth: Whisk in the flour to create a lightly creamy consistency.
Serve: Spoon the stew into bowls and enjoy warm — a taste of ancient Babylon brought to life.
