I love tomatoes, but in the middle of winter you can be sure that A) you're not getting the best and B) they likely traveled a long way to make it to your table. With that, I was absolutely thrilled to see the Rooftop Gourmet's Canned Tomato Guide.

- According to the article it's tremendously important to look at sodium content, a good product should have no more than 35 mg for a ½ cup serving.

- Choose whole tomatoes in order to get the best quality and then cut them accordingly.

- Tomatoes in juice tend to be fresher because they didn't go through the extra cooking step.

Other info on canned tomatoes:

- San Marzano canned tomatoes come from Naples, Italy, and are especially flavorful and good in sauces.

- Tomato paste is made from long-cooked tomatoes. Be careful about how much you use of this stuff because it can be super potent.

- Fire-roasted tomatoes are canned tomatoes with an added charred flavor.
