With everyday life busy as ever, some people choose "ready made" stuff, which, as an individual going to study the culinary art, I try to avoid. But, I do admit though, there are some foods out there that are better canned/packaged when going to be of use in a recipe. But not all. What are the ingredients you prefer being packaged/canned and what are things that are better made fresh? For example: puff pastry. yeah, that's a given because not many people can perfect making it. To have a frozen one can be quite convenient. Another example; canned tomato sauce. Now that, I cannot take. I prefer mine cooked fresh.
