The Real Secret to Choosing a Good Tomato Purée
There is no “magic code” that works across all brands and always tells you exactly how old a tomato purée is.
The most reliable approach is to consider several pieces of information together: check the batch number when possible, read the label, verify the origin of the tomatoes, and make sure the packaging is intact.
Commercial tomato purée can be a useful and high-quality ingredient in the kitchen. The key is to learn how to evaluate the product as a whole rather than relying solely on its appearance or on a single code printed on the package.
