In this how-to video, Gourmet Magazine editor Melissa Roberts shows you a quick and simple way to cut canned tomatoes. This technique will help decrease the usual mess. For this, you need kitchen shears or very sharp scissors, and obviously a can of whole tomatoes. Melissa suggests OXO kitchen shears, which you can take apart for easy post-cooking clean-up.
Simply stick the scissors into the can and cut the tomatoes. The amount of cutting you should do will depend on what type of tomato style your recipe calls for. After this, you can pour them into whatever appliance or dish you're using.
