How to use this prompt

The cut bar is what sells the swirl, so the prompt places one beside the loaf to show the layered interior the mould hides. Without it the surface swirl is only a promise. Cold-process soap has a matte, slightly waxy finish, so say cold-process and keep the light soft and diffused; hard light makes it look like plastic. The parchment lining is a practitioner detail that signals a real pour rather than a prop. A 4:5 crop suits a single loaf for a product listing. Keep the counter clean butcher block so the soap stays the hero.

Variations to try
