A rubber spatula is a flexible, flat-bladed kitchen tool used for mixing, spreading and scraping. It's typically made from synthetic or natural rubber with a long handle that allows you to reach into deep pots and containers easily. Rubber spatulas come in various sizes and shapes depending on their intended use - some are wider and flat for stirring or mixing ingredients, while others have a thinner edge for scraping the last bits from a container. They're commonly used in cooking, baking, and food preparation to move ingredients around without damaging them, as well as for cleaning up any residue left on surfaces.
