I'm quite new to cooking. I want to make spaghetti and all the recipes I've found for spaghetti sauce so far have required multiple types of canned tomatoes. However, I only have fresh tomatoes, nothing canned. I do have the basic spices (garlic, sugar, salt, pepper, etc), just no canned tomatoes.
Should I just finely chop my fresh tomatoes and put them in a pan with the spices? Should I add water or some kind of liquid?
