Another option is to use your sink (if the pot is small enough). Plug the sink, and fill it halfway with cold water, and add some ice if you can. Place the tomato sauce pot in the icewater, and stir continuously for about half an hour.

It won’t get ice cold, but it will get to room temperature, as long as you keep stirring all of it will be the same temperature.

If there’s no Tupperware on hand, you can use clingfilm or aluminum foil to cover the pot tightly. You can store the sauce with this method for about 24 hours before transferring it into a sealed container.

And if using a Ziploc bag, be sure to remove as much air from the sauce as possible. In fact, if you’re keeping the sauce in the freezer this may be the best option.

Put the sauce in small bags, or as much as you know you need for a portion, remove the air, seal it, and keep the bags in the freezer.
