Reading the bitterness
Raw foie gras has veins (veines), and a home-cooking guide by a French foie gras producer recommends carefully removing them before heating and cooking, a preparation step called déveinage. One producer explains that if the veins remain, they may give foie gras a slight bitterness. This is the producer's own explanation; it neither chemically identifies the component causing the bitterness nor measures it by sensory evaluation.
A cooking guide on another French producer's official website likewise states that, without this preparation, raw foie gras may develop bitterness and that the cause lies in the veins. It is notable that 2 independent producers agree in attributing the source of bitterness to the veins themselves rather than to the gallbladder itself; however, a shared limitation is that both accounts remain explanations based on producers' experience, without identification of bitterness components or quantitative sensory measurement.
