Traditional Ketchup: How Does It Differ From Organic And Low-Sugar Varieties?

Plain paragraph: traditional ketchup is mainly composed of tomatoes, vinegar, sweeteners, and seasonings. It has a characteristic high sweet and sour flavor that most people find delicious. However, it contains added sugar and preservatives that some may consider unhealthy.

Does Homemade Ketchup Have A Shelf Life?

Understanding ketchup’s types and their shelf life can help you determine the best one to use for your recipe. If you’re looking for a healthier option, you may consider organic or low-sugar ketchup. On the other hand, traditional ketchup is perfect if you want that classic sweet and sour taste.
