Water – The Good, the Bad, and the Funky

 Cool facts about water:

  • Most of Earth’s surface (nearly three-quarters) is covered with water, but only a small percentage of our water (2.5%) is fresh. The other 97.5% is salt water.
  • Of that tiny percentage of fresh water, most (roughly two-thirds) is locked up in glaciers and ice caps.
  • The only other places in the solar system where we’re fairly certain that liquid water exists are on the Jovian moons Europa and Callisto.
  • Every living organism on Earth needs water to survive.
  • Each day, we exhale a little more than a cup of water (as vapor).
  • Food is mostly water.

Water is an amazing substance. Many of us take its existence for granted. It can also absorb a large amount of heat, which makes it a great medium to use in cooking – steaming, braising, sous vide, proofing. Water is what makes CVap® technology so powerful, and so precise.

Water dissolves and contains minerals and other sediments. Some of these dissolved substances can do funky things to both you and your cooking equipment. That’s what makes it so crucial to clean and maintain your CVap equipment daily.

CVap technology uses water heaters to directly affect food temperature. As water evaporates from the CVap’s reservoir, it leaves behind the minerals and sediments were previously suspended in the water. Over the course of a few hours, mineral concentrations will naturally rise. If not cleaned properly, mineral concentrations can eventually reach a level that poses a contamination hazard to your food, and could damage to the equipment’s stainless steel interior. Adding a tablespoon of white vinegar or lemon juice to the water can help neutralize minerals, but based on your location, you may need to take additional water treatment steps before using that water in your equipment, or serving it to your guests.

There are several types of water treatment options to consider.

  • Sediment filtration removes suspended solids, reducing cloudiness. Cloudiness is usually caused by particles suspended in the water. These filters use a natural media (like sand) to filtering out the funk.
  • Carbon filtration also removes sediment, as well as chlorine, organic, bad odors and flavors. As the name implies, carbon filtration uses activated charcoal to absorb the nastiness.
  • Water Softening removes calcium, magnesium and other metals in hard water by using ion exchange resins. Minerals are flushed out via a salt solution.
  • Phosphates perform three broad functions: inhibit corrosion, chemically separate metals, and improve water quality by removing scale deposits, discouraging microbial film formation, and stabilizing free chlorine residuals.
  • Reverse Osmosis is by far the most thorough treatment option. It purifies water using applied pressure to force water through a semipermeable membrane, filtering out everything but water molecules. The pores in the filter membrane can be as small as the radius of some atoms. This means it can reliably filter out salts and metallic ions. There is a drawback – reverse osmosis creates a lot of waste water.

What’s all this got to do with CVap?

Every piece of CVap equipment is constructed out of stainless steel. Stainless steel is an incredible material, but it’s not indestructible. And water is one of the things that can flat take down stainless – or more specifically, the minerals found within water. That’s why daily cleaning is critical, not just for CVap equipment, but for any piece of stainless steel equipment.

Plating Perfect Pork Chops with CVap

One of the best things about CVap is having the ability to use it to handle precision cooking of center of the plate (COP) items without monitoring – or even having to check on it. For this blog post I got some beautiful Berkshire pork chops from Fossil Farms. I brined them in a 5% salt solution with honey and fresh thyme for two hours. What I wanted to accomplish was to have the pork chops done and ready for plating later in the day. I set up my CVap Cook/Hold to Doneness 145°F and Browning of 0. Once the CVap came to temperature and the display read “LOAD” I seared the chops and placed them on a rack inside a hotel pan.

The internal temperature of the chops at that point after searing was 85° F.

Once all the chops were seared and in the pan, off to the CVap they went.

With the CVap set to 145°F, all I had to do was wait for the moisture inside the chops to equalize with the moisture in the water pan. The Browning was set to 0 so the air temperature was 145° as well.  Basically, I was using a sous-vide method without putting the chops into a bag. A few hours later I made starch and a vegetable to go along with it.  When the pan was pulled out of the CVap all the chops were at precisely 145°F.

Pork chops cooked to perfection.

 

 

 

 

 

 

 

 

They were of varying thicknesses and weights, but all of the moisture inside the chops equalized to the temperature of the water inside the CVap. Wouldn’t it be nice to have the ability to do this with a large banquet where the party was delayed for some reason or another? When you use CVap to make your proteins this is a no-brainer.
