Quick Tip: How to Cool Soup Quickly with an Ice Paddle

2008_12_4-CoolingPaddle.jpgWith all the slow-cooking, slow-simmering recipes we're doing these days, we inevitably find ourselves close to bedtime with a fresh pot of soup still steaming hot on our counter. Here's a way to quickly get that soup to cool enough to stick in the fridge so you can carry on with the rest of your life!

 
 

Fill a plastic bottle about 3/4 full with water and leave it in the freezer for several hours until completely solid. After you've made your soup and are ready to pack it away, let it cool for a few minutes in the pot (so it's no longer boiling hot). Then gently stir it using the frozen water bottle.

It will take different amounts of time to cool your soup depending on how much you made. You can leave the water bottle standing in the pot while you do something else, but be sure to stir it every few minutes to agitate the hot and cold spots. Once the soup feels cool to the touch (that is, just below body temperature), it's fine to put in the fridge.

So far, we haven't had any problems at all with the normal plastic water bottles melting - this was definitely a concern of ours when we first came across this tip years ago, especially considering the concerns with heating plastic. But the frozen water inside seems to keep the surface of the plastic cool enough to prevent any melting, and in fact, the bottle actually stays fairly cool to the touch the entire time.

It's still a good idea to double check your bottle as you're using it. If the plastic is starting to feel soft and pliable, don't use that bottle!

You can also look into buying professional food-grade ice paddles. These typically start at around $15 for small paddles and increase in price as you go up in size.

Is there something wrong with putting the hot soup or braise in the fridge too soon? I have tempered glass shelves in my fridge but I usually just but down a thick kitchen towel under the pot to keep it from heating the glass too hot.

Good question, Caw - it can be dangerous to put really hot foods in the fridge because it raises the overall fridge temperature and the cooling mechanism in the fridge can't keep up. This can potentially cause other foods to spoil and/or make you sick!

this is a great idea, we ALWAYS are in this situation.

don't want to refrigerate too early because the heat of the pot will warm up the fridge, spoiling milk, etc.

sometimes we just stick the pot outside on the balcony...

One problem is that the soup could warm other things in the fridge. Also, if the soup isn't cooled quickly enough, all sorts of nasty bacteria has opportunity to grow in it. We had a big chili supper at our church last winter, and all the hot leftovers were put into the refrigerators to use for chili dogs a couple days later. When it was taken out, every crock of chili was spoiled because it wasn't cooled quickly enough.

Since I don't usually keep water bottles in the freezer, I fill a ziploc bag with ice cubes and put that in the hot soup (the bag will keep the soup from getting watered down as the ice melts). Stir gently until the soup is cool and remove the bag before refrigerating.

You can also use ice packs that you would normally have in the freezer for lunch boxes.

I run into this problem a lot, and i usually just wind up leaving the pot of soup on the counter overnight and then throw it in the fridge. I've never gotten spoiled soup or even gotten a hint of being sick.

The way i figure, if you've been cooking this thing for a while, presumably boiling it most of the time, whatever bacteria was in there is good and dead. If you leave it covered overnight, there's no new bacteria getting introduced to the pot, and therefore nothing to go bad.

Secondly, its soup. If you're like me, you reheat it to a pretty high temperature, again killing any potential bacteria floating around in there.

I know it wouldn't pass in a food safety class, but like i've said, i've never ever gotten sick.

Caw - I had the same question, and according to my mother, you are supposed to cool things first because otherwise they raise the entire temperature of the refrigerator and aside from the spoilage issue raised above, it also makes your refrigerator work harder to cool everything else, so it's not good for your carbon footprint or the life of the machine.

You're really better off dividing the soup or stew into smaller bowls and putting them in the fridge, rather than waiting for it to cool down. Meat, poultry and seafood shouldn't sit around.

Also, don't cover meat until it cools down.

I just ran into this issue last night! I've never thought of doing this, brilliant, thanks.

I saw Alton Brown do this awhile back for, I think, a big bucket of stock he'd made! It really is such a great idea.
