Traditional Italian tomato sauces for pasta typically do not include milk or cream. In classic Italian cuisine, tomato-based pasta sauces are usually made with a few simple ingredients, such as tomatoes, olive oil, garlic, onions, herbs (like basil and oregano), and sometimes a pinch of red pepper flakes for a little heat. These sauces are often known as marinara or pomodoro sauces.
The use of milk or cream in tomato sauces is more common in certain non-Italian cuisines, particularly in some American or British adaptations of Italian recipes. For instance, in the United States, you may find variations of tomato sauce that include cream to create a creamier texture and milder flavor.
It's essential to remember that Italian cuisine varies by region, and there are many different pasta sauce recipes across Italy. However, if you're looking to prepare a more authentic Italian-style tomato sauce, skip the milk or cream and stick to the traditional ingredients for a true taste of Italy.
