Yesterday, I was halfway through a recipe when I realized it called for puréed tomatoes, and all I had was diced. I definitely wasn't going to abandon ship and start over on something else, but I didn't want my sauce to have the wrong texture, either. So, I did a quick search and found that I could use my metal sieve to purée the tomatoes.
This technique works for a lot of different foods, but most of them have to cook for a while before they're soft enough to push through the sieve. I let my tomatoes simmer for about 30 minutes because I was in a hurry, but it was still pretty difficult to push them through, so let yours cook for longer if you have the time.
