Two things about cooking a big batch of something. You need to get it in the fridge, and you need it to be cold when you put it in, otherwise the warm food will over-work your fridge and everything else will get warm.
Last night, while getting ready to pack up the tripe stew I made, I stumbled on a quick and easy way to do it!
I put the stew in baggies and set them back in the (now washed) pot. Between the baggies of stew I slid frozen gel-packs—the same kind you use to chill food when camping.
Then, remembering that air is an insulator and water is a conductor. This is why Jack died and Rose lived – the cold water lowered Jack’s core temperature quickly. Yes! There was room on the door! If he’s gotten out of that cold water he would have lived!
But we do not want anything to live in the food we are chilling, so faster is better. The water allows for faster equalizing of the temperature differential between the frozen gel-packs and the food, so the food drops to a refrigerator-able temperature nice and fast.
Instead of taking all night, the pot of tripe stew took a little over an hour.
