Giblet Gravy

Combine turkey giblets, neck, and 4 cups water in a saucepan; bring to a boil. Reduce heat to low and simmer until broth is reduced to 3 cups, about 1 hour.

Strain broth and reserve 1/2 cup of giblets.

Whisk 1/2 cup cold water and cornstarch together in a small bowl until smooth.

Combine strained broth and turkey drippings in a saucepan over medium heat. Whisk in cornstarch mixture and bring to a boil.

While broth is coming to a boil, finely chop giblets.

Reduce heat to low; stir chopped giblets and hard-cooked egg into the gravy and season with salt and black pepper. Simmer until gravy is thickened, about 5 minutes.
