A bacon press, also known as a cast iron steak weight press or cast iron bacon flattener, is a kitchen utensil designed to improve the cooking process and results of bacon. Typically made of heavy-duty materials like cast iron, a cast iron steak weight press is a flat, weighted tool that is placed on top of bacon as it cooks. Its purpose is to ensure even cooking, prevent curling, and promote crispiness by pressing the bacon flat against the cooking surface.
