can you render fat with sous vide

Sous vide is a cooking technique used by fine dining establishments to slowly cook foods in a sealed bag at low temperatures. Sous vide machines ensure that your steak, roasts, and other foods cook at a precise temperature, so they come out succulent and delicious every time. If you enjoy fine cuisine but want to reduce the time you spend in the kitchen, a sous vide machine may be the perfect device for you.

To help you on your way to becoming a sous vide expert, we have compiled a list of some common sous vide mistakes to avoid. Recommended Videos

Do you love tender and juicy rib eye steak with the fat rendered so perfectly that it melts in your mouth? After watching videos and seeing pictures of a perfectly cooked sous vide steak, many newbie sous vide cooks make the mistake of assuming steak fat is going to behave the same way the meat does. But, this is a mistake, as fat and muscle tissue have different chemical compositions, and therefore they behave differently when you cook them.

When you cook a medium-rare steak sous vide, you’re cooking it at a constant temperature of between 129 and 134 degrees Fahrenheit. At this temperature, it takes quite a long time for fat to render. Because of this, many sous vide cooks complain of “rubbery” fat, or fat that is overall unappetizing.

To eliminate the “fat problem” when cooking steak sous vide, you have a few options. You can pre-sear your steak before placing it in the water bath. Some cooks recommend this for more marbleized cuts, like rib eyes. Others say cooking your meat for a bit longer, while still staying within the recommended ranges. You can also trim off the fat, or choose a cut of meat that’s leaner, like sirloin or fillet mignon. It’s also best to avoid methods like “salt drying,” as they typically don’t produce good results. Remember, to get the browning produced by the Maillard reaction, you’ll want to finish the steak on the stove or grill.

You can do it sous vide if you’re wanting it to be a “set it and forget it” situation. You’re still going to have to boil off the water when it is done. Or stick it in the fridge, and pull the solidified fat off. I used a crockpot to render bear lard a couple of years ago.

Forgetting eggs are fragile

Second to steaks, eggs are probably the best food you can make sous vide. But, if you just chuck them in the water bath, only about 80 percent of your eggs will make it out without damage. To protect your eggs, just place them in a sous vide pouch; they’ll be just as delicious, and all of them will likely make it out intact.

Imagine you’re having the boss over for dinner after work, and you want to impress the head honcho with your awesome cooking skills. So, you put your sous vide pouches in the water bath before work, and head out for the day. But, when you return home, half of the water has evaporated from your water bath, your pouches are only partially submerged, and your dinner (and potentially your sous vide machine) is ruined.

To avoid this, cover your container with plastic wrap so the water that evaporates goes right back down into the bath. Also, always make sure to follow your manufacturer’s instructions on leaving your machine unattended. ChefSteps

Read, read, read, practice, and then read some more. Reading all of the instructions for your machine, researching other people’s experiences, and practicing different recipes will help you learn how to cook your meals to perfection.

Even though people say sous vide is easy, you can overcook your food. The food continues to cook after it leaves the pot, unless you place it in an ice bath. Also, when you go to sear your meat, you can easily overcook it during searing, especially if you’re using a thinner cut. Some chefs say that you’ll get the best results if you use a very thick cut of steak (like two inches or even thicker).

When you season foods and cook them on a stove top or on a grill, some of that seasoning falls off onto the pan or even into the air. When you season foods you’re putting in a sous vide pouch, however, that seasoning has nowhere to go but into your food. If you season your foods heavily, they may come out overly salty and, quite frankly, kind of gross.

If you stick with fresh spices and aromatics beforehand, you can always add any extra seasonings afterwards.

Poorly handling sous vide pouches

If water from the bath gets into you sous vide pouch, this can create something that looks more like a mess than a meal. You want to make sure your sandwich bags or vacuum-sealed pouches are properly sealed before you submerge them. If you’re really serious, you might even consider silicone bags.

When it comes to sous vide, tongs are not your friend. They can smash your delicate fish fillets. Also, picking up sous vide bags with sharp tools like tongs can puncture your bags. Foods like asparagus, nuts, or other foods with sharp stems can puncture your bags if you don’t use caution when placing them in your sous vide pouches.

Cooking for a large group? You can put several cuts of fish or other meats in the same pouch. But, if you neglect to stir the pouch around from time to time, you’ll end up with one big giant connected piece of meat, instead of delicious single portion fillets.

Floating can also be an issue. Make sure you weigh down your bags down, clip them to hold them in place, or follow your manufacturer’s instructions for how to prevent floating. ChefSteps recommends placing a butter knife or spoon in the bag with your food to weigh it down.

At what temp does beef fat render? Beef fat renders at 130-140°F (54-60°C). This is a process you want to take slow, so maintain this temperature while cooking for several hours.

What is the best way to render fat?

There are two ways to render—with dry heat or wet heat. Dry heat means you are cooking just the fat on its own, whereas wet heat includes a bit of water. You can use a crock pot, stovetop, or oven with either method. The fat is slowly cooked until it melts and is then strained of impurities from the cooking process.

Will fat render in boiling water?

Place the fat into your pan, then add enough water to cover the bottom of the pan by about half an inch. Place the pan over a medium flame, until the water starts to boil, then turn heat down to low. Cook gently for 1-2 hours, stirring every so often until most of the fat has rendered.

How do you know when fat is fully rendered?

Once the crunchy bits of heaven have all sunk to the bottom, your fat is officially rendered, and you have a crunchy snack waiting for you. Strain the fat through a fine mesh sieve, or chinois if you have one.

Does SousVide render fat?

Sousvide can render fat if warm enough (135), but in shorter cooks for steak it will not compare with dry hotter heat. For that reason I prefer to reverse sear ribeye and steaks with lots of fat. Longer cooks can render fat at cooler temps (131 or so). You won’t get as much rendering with SV because the temps are generally too low.

Is Sus vide good for lean meat?

A big problem with traditional fatty meats such as brisket, pork butt, or such is that Sous Vide temperatures don’t get the meat hot enough to render the fat. Lean meats are hard to get tender because of the lack of fat, so Sous Vide is better for lean meat.
