A great tip from Rachael Ray... When you buy one of those 6 or 12 oz. cans you're never going to use all of it in one meal... unless you've got taste buds of steal.
So, here's the trick - take all of the ribs and seeds out of the peppers and then puree the peppers along with the remaining sauce. Scoop it into saran wrap and form a log. Then put the "log" in a zip lock, label it, and stick it in the freezer. It keeps for forever and is a great way to use all the can. I tossed a many of leftovers... or used all my chipotle recipes in one week to use it up. Which got real old.
When you have a recipe that calls for Chipotle Peppers in Adobo Sauce all you do is just take a knife and cut off the amount you need. Which is why you do a log so it's easier to cut and measure out then a big ball of it. So sweet! I love the tip and have been doing it for years.
