That is so true. But remember - safety first! Always make sure to check the expiration date on your cables, so they don't spoil. I never keep cables for more than a few months as they start to sound dull and wear out after that. Wait no, that's guitar strings. Anyway, I'm sure the same theory still applies. Most cooked cables will last about four years and after that they should be replaced, as should the cable cooker itself. You might want to invest in a cable cooker cooker too, as the cooker will not perform at maximum burnosity unless it has been carefully matured electrically. Don't rule out the gains achieved by a power cord upgrade on your cable cooker cooker either, as line noise can create permanent reflections within the cable windings, much like a seashell captures the sound of ocean waves. Omit this and it's likely your stereo will sound like total shit.
Also, if you don't feel like waiting around you can simply purchase an inexpensive TIG welder retrofitted with RCA jacks and binding posts and use your cables for that. However, the ultraviolet light given off is known to adversely affect the range of 8360-12,475Hz so be sure to wrap your cables in an anti-UV coating before welding. After cooking is finished remove the cables carefully using a teflon spatula and let them cool at room temperature for at least 3 hours. When in use make sure the barrels are not facing north for best results, and only on days when solar flare activity is low.
