Though I am typically in "Resolutions" mode until the end of January, I am not talking about about working out at the gym every day or eating carrot sticks instead of a Snickers bar for a 4 pm snack. When I say "de-fat," I am talking about taking the fat out of your broth when you make stocks and broths. I have been in a soup-making frenzy the past few weeks and making stocks has been on the brain.How do you de-fat?
For the longest time, I didn't do it because it was too difficult a task. I had to very carefully skim the top layer of stock with a shallow ladle to catch the liquid fat that was floating on the surface, which never seemed to be a very thorough method.
The last few years, I have been turning stock-making into a multi-day process. It requires simmering the stock all day on the first day, letting it cool, then chilling it in the refrigerator for the fat to harden. I'd simply remove the layer in one large sheet. It felt like I was removing almost all of the fat, and it seemed faster and simpler to just trash a solid sheet of fat. However, it does take two days from start to finish.
Of course, I could simply shout the battle of cry, "Fat means flavor!" and forget the whole thing.

At home it's generally fine to have stock-making be a multi-day affair; if I need the stock the day it is simmering, I just strain it directly into whatever I need it for and just leave in the fat for that one dish.

There's the fat tail of a chicken, the fat of pork ribs, the fat on a steak at times, and the fat you find in pork and beans which I guess represents the pork you think you're going to get with the beans. When I see a box of some dessert and it says fat-free, often that means flavor free too. People who eat veggie burgers to not eat fat might be health conscious. But you know what goes good with veggie burgers? MEAT.

You pour the stock and the fat floats to the top, you don't pour from the top, instead the spout is separate and is attached at the near the bottom of the cup so that it pours out the broth leaving most of the fat. You have to pour carefully and you will get a little fat. At least you can defat without chilling

Once I have it in a fat separator--looks like a watering can with the spout starting at the base of the container--it's a piece of cake to decant the stock leaving the fat behind.

There's aways the écumer, dépouiller, écumer, dépouiller routine (clearing the scum, then removing the skin that forms), but I think you'd need a French chef yelling in your ear to resort to that. Otherwise, yeah, cooling, chilling, and scooping the solidified fat is the best way to go. (But the écumer and dépouiller will result in some nicely clear stock as long as you keep it at a simmer and never at a hard boil!)

For larger batches of stock (2 gal or more) i use a defatting measuring cup AND i refrigerate & spoon off fat...but for small batches, the little cup thing works great. But boy, are they a pain in the ass to clean, even in the dishwasher. My advice: If you get one of these nifty little devices, get the biggest one you can find, you can keep pouring in the liquid and the fat will keep rising. OH, and i always pour the first little bit back in the pot, to remove the fat in the spigot. That way, it will get removed instead of poured the storage vessel.

My recipe for stock is done over 3 days, which I don't mind since I don't have to pay attention to it aside from turning it on and off.

One thing that I've heard of, but never tried, is ... Take a ziploc bag & fill it with ice cubes & seal the bag ... Then drag it slowly around the top few inches of the broth/stock/etc ... The grease/fat is supposed to coagulate around the ice bag ... I guess you could consider it the "quick chill w/o the fridge" routine ...

The fat cools and sticks to the outside of the bottle, and this also has the side effect of cooling the stock quickly from the inside out, so it can be refrigerated.

The most important thing though is cooling your stock as quickly as possible so it doesn't stay in the "zone" for very long. But letting the fat harden is by far the easiest way to get rid of the fat, and to keep it if you care to. In a restaurant I worked in we used to keep the beef fat on occasion for use in other foods.
