Rinse the Marinara Jars With a Little Wine
Whether you’re using a can of cooked marinara or making a sauce from scratch with canned plum tomatoes, there will always be some jam, red residues on the bottom and sides of the container, whether it’s a plastic container, glass, or aluminum.
There are never so many leftovers that it would be terribly bad to throw away, but chances are that you probably want to recycle the container and you can’t throw a dirty can of tomato paste or can in the trash can. … (Do you want ants, rats, and other parasites? Because this is how ants, rats, and other parasites appear.)
So, if you are going to rinse tomatoes from a jar or tin can, you can toss them in the sauce or rinse them with wine. Even cheap, slightly oxidized red water will add more volume and depth than plain boring water. You can use the wine infused with tomatoes to remove the frosting in a skillet with onions or sausage, or add it directly to the simmer and let it cool along with the rest of the sauce. In any case, you will feel like an example of culinary excellence.
If you are working with a pitcher, simply pour the wine into the pitcher, close it and shake; If you are working with a can, pour the wine into the can and swirl it a few times (and perhaps scrape the sides of the can with a spoon or spatula). Then, pour the wine into the sauce or skillet. Then rejoice, because spaghetti is coming. (And yes, you should probably rinse the container of tomatoes one more time before throwing it in the trash can – that’s a polite thing to do.)
