What is the best way to render duck fat?

Looking for step-by-step instructions and/or videos.
Personal experience appreciated!
This is for making Duck Confit which will go into the French dish, Cassoulet.

MAKES ABOUT 1 1⁄3 CUPS

The great thing about rendering your own duck fat is that you end up with a batch of cracklings—delicious to snack on, sprinkled with salt.

Skin and fat from 1 whole duck, avoid tail and neck
areas

1. Cut skin and fat into medium pieces and put into a medium heavy-bottomed pot. Add 1⁄2 cup water and simmer over medium heat until water evaporates and skin pieces are crisp and have released all their fat, about 1 hour.

2. Strain clear golden fat through a sieve. Store duck fat in a sealed container in the refrigerator or freezer

Duck fat contains 35.7% saturates, 50.5% monounsaturates (high in linoleic acid) and 13.7% polyunsaturated fats.(which contains Omega-6 and Omega-3 essential oils). This compares to olive oil which is: 75% monounsaturated fat (mostly oleic acid) 13% saturated fat and 10% Omega-6 linoleic acid and 2% Omega-3 linoleic acid. The main difference between chicken, turkey and duck is that duck contains more linoleic acid, which chicken and turkey contain a higher amount of polyunsaturated fats

Pros and Cons for each method:

Method I provides for a clearer more pure form of duck fat. Method II retains water which can decrease shelf-life. In addition Method II requires constant watching during the rendering process. However for small amounts of duck fat Method II is preferred.

Note: Duck fat which may contains water should not be added to a very hot pan since the fat may splatter. Add to a low heat pot and allow the sizzle to die down first.

I think it is probably hard to convey, in writing, exactly how giddy this photo makes me. Do you see that beautiful, clear, golden liquid? That’s duck fat. Otherwise known as, “one of the most delicious substances you could possibly ever consume.” Also known as, “nearly impossible to find without paying a fortune.” Finally, known as, “the substance Katy is so in love with that her parents worry she will die of a heart attack at 26.”

Heart heath aside, I am so incredibly excited to have this little jar in my fridge (and two others in my freezer). And I am extra, extra, extra excited to share it with all of you! So let me start at the beginning.

Sometime in early 2008, I came to the conclusion that many dishes, be they vegetable, soup, or sauce, could be improved with a richer, more flavorful cooking fat. I like olive oil as much as the next girl, and I’ll use butter on occasion, but I was intrigued with the idea of cooking with other types of fat. I experimented with sesame oil, dabbled in truffle oil, but finally I realized what my dishes were lacking: duck fat.

http://www.sugarlaws.com/wp-content/uploads/2008/03/fat3.jpg

So, I started looking. None of the grocery stores in my neighborhood sell duck, except in the prepackaged D’Artagnan ziplocs — no duck fat scraps to be had there. But in the back of my mind, I remembered the meat sellers at the farmer’s market. If you can buy a duck breast or leg at the farmer’s market, I figured, the rest of the bird is pretty likely to be for sale as well (the same is probably true of a good butcher, if there’s not a farmer’s market near you).

Sure enough, the following Saturday, I asked at the farmer’s market if the duck meat vendor had any fat for sale. The man gave me a curious look, and said, “we don’t bring it every week, but if you give me your name a week in advance, I can take an order.” I gleefully gave him my name, and asked for a pound of duck fat. And as I was about to walk away, he called out, “I’ll just get you the actual fat — you’ll have to render it yourself, is that ok?”

Brightly, I responded, “of course!” Inwardly, I thought to myself, “um, what is rendering, exactly?” And, I will admit, I was a little bit intimidated when I was handed this:

http://www.sugarlaws.com/wp-content/uploads/2008/03/fat5.jpg

Somehow that is not exactly the culinary delicacy that I had in mind. But after a little bit of research, I did figure out how cooks render what’s pictured here into that gorgeous golden liquid that one can actually cook with.

And now I’m going to share it with you, because it’s actually quite simple.

Take the fat from the animal, and put it in a flying pan. Cover it with about 2 cups of water per pound of fat, so that the fat is entirely submerged in water. Turn the heat on the burner as low as you possibly can, and just barely simmer for about 60 or 90 minutes, until the water has cooked off and you are left with a beautiful golden fat.

Here’s what it looks like after about five minutes:

http://www.sugarlaws.com/wp-content/uploads/2008/03/fat61.jpg

After fifteen minutes:

http://www.sugarlaws.com/wp-content/uploads/2008/03/fat7.jpg

After forty five minutes:

http://www.sugarlaws.com/wp-content/uploads/2008/03/fat8.jpg

When it starts to look as though the simmer is dying down, watch the fat very, very carefully. It should be a warm golden color, with little lighter-colored bubbles emerging from the center of the pan where the heat is strongest (the water). As there is less and less water, those bubbles will become closer and closer to a boil, and the remaining liquid will turn a darker golden. Eventually, the boiling bubbles will suddenly become much smaller, just back to a bare simmer, which means all the water is gone. At that point, remove the fat from the heat immediately — if you burn the fat, it’s useless and you have to start all over.

In my (humble) opinion, it’s better to have a slighly watery duck fat than to lose a whole batch that you burned, so once it hits the right color and the bubbles start to die down, you’re done.

Next, let the fat cool in a heat-proof container, uncovered, for about fifteen minutes. When it has cooled slightly, strain it through a fine mesh strainer at least three times, and pour it into a small glass container or two.

Allow to the rendered fat to cool, uncovered, for about 2 hours at room temperature, than transfer to the refigrator for 24 hours (it will solidify again). After 24 hours, move any containers that you plan to freeze to the freezer.

My pound of duck fat made about 1 cup of rendered fat. It will keep several months in the refigerator or up to a year in the freezer.

Here's how to render duck fat:

Take the fat from the animal, and put it in a flying pan.

Turn the heat on the burner as low as you possibly can, and just barely simmer for about 60 or 90 minutes, until the water has cooked off and you are left with a beautiful golden fat.

It's pretty easy. It just takes some time. But you'll have something exceptional when you're done.

Well, that only works if you've already roasted the bird. During roasting, you can capture a ton of fat simply by putting a pan of water below a slotted rack.

EDIT: I just happened to discover that the Mahalo CEO is apparently a cooker of Cassoulet. You might just want to ask him a direct question about it as well if you're not terribly happy with the answers you get here.

I cooked a duck, once. It was a fascinating experience, although not a terribly successful one. These were the days when I had a one-bedroom apartment with a teeny kitchen and very little in the way of tools.

One thing I remember very clearly is that the duck rendered a LOT of fat. I was surprised at how much fat came out of the relatively little duck.

I also did not cut it up and just scored it then roasted it on a baking sheet. This was a bad idea. In the future, I'd take apart the duck, then do Alton Brown's recipe where he puts pieces in a steamer with water in the bottom and steams for 45 minutes. Then boils of the excess water and voila, liquid duck fat.

I've got to assume you are a fairly accomplished cook already, hence why you are trying an ambitious recipe like Confit. Not hard, mind you, just a bit of a learning curve is all.

Here's a few good videos for you.

Alton Brown's Duck recipe is for roast duck, but gives good info on rendering and how to deal with the duck fat. Also, great Monty Python send-up and the whole ep is funny as heck. Part One brings the funny:

And part two deals with the rendering. At about a 2:20 and then again at 6:00 in when he talks about rendering.

http://www.youtube.com/watch?v=Frn-M8HnlP0


The Gourmet Magazine people are pretty good for cooking technique recipes. Not quite Cook's Illustrated good, but pretty good nonetheless.

http://www.youtube.com/watch?v=eng_3c3XFxw


Cook's illustrated has a recipe for Confit and Cassoulet in their America's Test Kitchen cookbook. I've not tried this one, but I trust the accuracy and precision of the CI food and recipes.

Sharp scissors and kitchen knives is important unless you can find somebody to cut your duck for you.

Good luck and have fun!
