I had one of these. Know what works exactly the same, perhaps even better? A wire rack for baking (cooling cookies, etc) or just about anything that props up the frozen thing so that air can flow over and under it.
Thanks for that. I was always curious, but it felt a little woo-woo.
I have plenty of extra racks, I will try that.
I’ve used these for years. It’s not just the air-flow - it’s the metal they are made from that allows it to work so well:
They’re made from heat-conducting metal — like aluminum — that efficiently transfer the warmer temperature of your kitchen to the colder temperature of whatever you’re defrosting. The cold temps in the meat (or other frozen food) are then transferred to the tray. In other words: Science!
