So I have many times, while I am making multiple meals for a few days, 'recycled' the left over juices from a dish to cook another dish. Thats good so far right? When I got home from work and scooped the little bit of stew meat leftover from lunch, I had a lot of juice/sauce or whatever you wanna call it left. Is it ok to use this recycled juice a third time or is that plain nasty? or rancid?

Am I being too 'thrifty'? lol
