Do dormant cables need "RE" Broken In? If so how long can they sit dormant?

I have a few extra components around that allow me to hook up cables to,break them in. I got a connector converter so I can power my extra refrigerator through an audio power cord… hence cooking it… without harming any chickens. 
 

Those cable cookers are expensive.

Can anyone qualified clarify how cables are "cooked"?

Isn't the purpose of "cooking" cables just a matter of moving valence electrons around to break in a cable?

Can't someone just have an appropriate source of current and voltage such as a power supply of the proper voltage connected to the cables and then to a lightbulb, motor (or similar) and accomplish the same goal for pennies on the dollar?  This is just how my mind works... 

Anytime I've reinstalled cables that have been in storage for months, it has taken around 200 hours for them to stabilize. Sometimes you hit a wall where they don't seem to be improving. In those instances, I disconnect them and reinstall them and that seems to hasten the settling a bit. Bass seems to come and go as they settle and imaging seems to be the last to arrive. Tara Labs seem to take the longest.  

It’s pretty crazy, but when I was reviewing cables even having them outta the system for a half hour they’d need a minute or so to settle back in.  Not sure about cables they’ve been sitting dormant for a while, but it’s definitely a thing IME.

I have to agree with you. The Monster M2.2's (Dormant for many years) that I purchased have been playing daily for a couple of week's now and I swear things are opening up even more. Could be my ears...however, I was doing some serious listening last night and I swear the cables are sound better than the week before. I keep the stereo on quite a bit for background listening.
