Crushed Tomatoes: Your Ultimate Guide
1. History of Crushed Tomatoes:
The tomato itself originated in South America, with evidence suggesting its cultivation as far back as 700 AD by the Aztecs and Incas. Tomatoes were introduced to Europe by Spanish explorers in the 16th century. Initially, they were viewed with suspicion and were largely ornamental. However, the tomato gradually gained popularity as a food, particularly in Italy. The use of crushed tomatoes, as we know them today, likely evolved alongside the development of tomato-based sauces and stews, becoming a common ingredient as tomato cultivation spread. The technique of crushing tomatoes to break them down, release their juices, and create a smoother texture became a natural progression in their culinary application.
