So how do you bake your resistors?

I've found a resistor recipe that's to die for, I thought about keeping it to myself but this recipe's so good I just had to share.

Allen Bradley RESISTORS special treatment method
As stated, Allen Bradley resistors are carbon composite. Being made of organic material, they do have the tendency to absorb water from the atmosphere. This absorption can increase the actual resistance of the component, hence the slightly higher-than-normal tolerance published on this page. To fix this, remove the water from the component and seal it. The best method is to place the resistor/s on a baking tray, set your oven to 80 degrees centigrade and leave it in the oven for 8 hours. The secret is to remove the moisture slowly. If you rush, it will become noisy in the circuit. Once cooked, seal the body of the component in Shellack (preferably the flakes) to stop further water absorption. At the end of this procedure, you will have much lower noise and more closely tolerant resistors. Special thanks to Colin Cornish for this excellent tip


So how do you cook yours? I'm thinking low and slow on a charcoal bbq.
 
What an epiphany!

I've been doing it all wrong.

I've been poaching mine in water with a little bit of vinegar, and they all come out blue...

I re-use the poaching concoction for my breakfast-eggs; up to 750k to 820k tastes great, but if you poach anything in the mega-ohm range, the eggs will be bitter.

Just be sure to wipe the leads down with a scotch-brite as the smoky film makes them hard to solder!
 
Yep, I ate a few cakes/muffins my sister baked.

However, an Easy-Bake Oven is no match for a 5 gallon jug and hot-tub. Though I bet afterward hot-tubbin' there'd be a hankering for Easy-Baked muffins/cakes...
