I cook a lot of Italian dishes. My wife likes tomato sauce, but can't stand chunky tomato flesh. And so I have learned to make these dishes with strained tomatoes.
Recently I came across a recipe that called for diced tomatoes, and canned tomato sauce. I replaced the diced tomatoes with strained tomatoes and noticed that it looks a lot like the tomato sauce. They seem remarkably similar.
Are these two products the same? If not, how do they differ?
