Sous vide cooking raises its profile

Over the past few years, appliance manufacturers have made sous vide cooking, once the exclusive domain of high-end restaurants, available to anyone who wants to add the unique technique to their cooking repertoire. Sous vide involves sealing food in a plastic bag and cooking it in heated water. This allows the food to be cooked at a constant, precise temperature.

While sous vide is beloved among steak aficionados for its ability to produce precisely cooked cuts, it can be used on all types of foods, including other meats, vegetables, seafood, eggs and desserts.

We caught up with Derek Gaughan, who runs the product-review and recipe website Sous Vide Guy, for a talk on the growth in sous vide cooking, its benefits and how home cooks can get started.

“The process has been around for quite a long time, but for the longest time it was expensive to create and use,” Gaughan said. “Since about 2012, competition has been increasing, with more manufacturers coming out with products, prices going down, and features increasing.”

These days, sous vide cooking at home is most likely to involve one of two appliances: an immersion circulator that keeps water at a precise temperature, or an all-in-one sous vide machine that holds both the water and the food.

“The all-in-one machines take up a little more space, but you have everything you need,” Gaughan said. “The immersion circulators can fit right in a drawer.” However, you’ll also need a container for the water if you opt to use an immersion circulator. Gaughan recommends polycarbonate containers. When choosing a container, keep the size of the meals you’ll be preparing in mind.

Food is cooked in a sealed plastic bag, which allows it to hold on to its natural juices and flavor. While many opt to add a vacuum sealer to their sous vide toolbox, Gaughan says a heavy-duty sealable freezer bag will do the trick.

So what’s a good food to start with for those looking to dive into the sous vide pool? “You have to start with steak,” Gaughan said. “When you cut into the steak, it’s the same color throughout. My particular favorite is tri-tip. It’s usually cheaper per pound because it’s a tougher cut, but sous vide makes it more tender.”

The rise in popularity of sous vide has given way to new appliance features, including Bluetooth connectivity. “You can start cooking, turn on the device and monitor the temperature from your phone, look up recipes, or instantly set the temperature according to the recipe,” Gaughan said. “Some people fill their water bath full of ice in the morning, then turn their device on through WiFi when they’re about to leave work.” Other sous vide devices are now integrating voice controls, Gaughan said.

What’s the best way to get started? “Grab a cookbook,” Gaughan said. “When you first get a sous vide device, it’s odd, because you’ve never cooked something by just placing it in water. Read up on it before you do it. Read about the pasteurization temperatures. It’s a lot easier than you think.”

Counterfeit water filters: Your health and property on the line

Not all replacement refrigerator water filters are created equal, even those that may appear from the outside to be exactly alike. Unfortunately, many counterfeit and deceptively labeled water filters manage to find their way into the U.S. It’s a stretch at best to call these knock-offs “filters,” and the tests show it. If you’re wondering what’s inside the phony filters, it varies. Some contain no more than shredded newspaper.

 

As part of AHAM’s Filter It Out campaign, experts conducted tests of legitimate replacement water filters versus a counterfeit. This photo hows the results of the testing, which was performed by NSF International.

Why it matters: The blue dye present in the water after it was run through the counterfeit filter represents the contaminants that would have made it into your body had the counterfeit been installed in your refrigerator. Those could have included lead, mercury, herbicides, pesticides, asbestos and pharmaceuticals. As if the risks to your health weren’t enough to worry about, the filter, since it wasn’t designed to fit your refrigerator, could also cause leaks, which can lead to serious and expensive property damage.

The good news is that since many of the counterfeits are sold online by independent sellers, you can reduce the likelihood a counterfeit water filter will end up in your refrigerator by purchasing your replacements from reputable sources. And remember to replace your filter every six months with a model from a manufacturer who will stand behind its products.

A spring cleaning appliance checklist

It’s tough to imagine tackling the various spring cleaning projects around your home without essential cleaning appliances like vacuums, washers and dryers. In fact, some of your appliances are so essential to keeping your home clean that it’s easy to forget that cleaning your appliances should also be part of the annual springtime ritual of scrubbing, polishing and purging. These regular maintenance steps are also essential for keeping your appliances in top shape. Here’s a quick checklist of spring cleaning tasks that will keep your home sparkling and your appliances in top shape:

  • Refrigerator coils: The dust, dirt and debris that builds up on your refrigerator coils can make the appliance use more energy to keep what’s inside cool. A coil brush and vacuum will help you with the coil cleaning and removing other dirt that has accumulated behind or under your refrigerator.
  • Clothes dryer: Your interior venting system, or the material that leads from your dryer to your dryer vent, should be cleaned once a year by a qualified service technician. Blockages can lead to longer drying times. Also, check behind your dryer and remove any trapped lint and debris, and remove lint from in and around the drum.
  • Oven and range: Spills and built-up residue can hinder your oven’s performance and affect the flavor of the foods you cook. Refer to your oven’s use and care manual for specific cleaning instructions, but warm soap and water or vinegar and water are unlikely to damage any finish.
  • Vacuum: Replace bags and filters and check your vacuum’s use and care manual for guidance on belt replacement.
  • Water filter: Replace your refrigerator water filter every six months, or on the schedule recommended by your refrigerator’s use and care manual. It’s extremely important to purchase replacements only from reputable sources to reduce the chances you’ll end up with a counterfeit model.
  • Indoor air: April showers may bring May flowers, but with those flowers, buds and blossoms come less welcome allergies. The EPA estimates that indoor air may contain double to five times as many pollutants as the air outside. Room air cleaners, vacuums and washing bedding in hot water can help you fight the main indoor allergens: pollen, mold and mildew, animal dander and tobacco smoke.
