Thermal immersion circulators are used not just to maintain precise temperatures in liquid-based ingredients, but can also be used to cook sous vide dishes, which are chopped fruits and vegetables, meats, and other ingredients sealed in sealed vacuum-packed bags, slowly cooked in the heated water.
They are also popularly used to sterilize or pasteurize an assortment of food products.
The versatility of a thermal immersion circulator has seen them become an increasingly popular choice amongst home chefs and professional kitchens. Thanks to increasingly advanced technology, they are now much more affordable and offer much more control than they did in the past.
What is the difference between sous vide and immersion circulator?
Sous vide and immersion circulator are two different types of food preparation techniques, often used in combination with one another. Although they are both used to cook food in a sealed bag and at a precise temperature, they have some key differences between them.
Sous vide, which means “under vacuum” in French, is a cooking method in which food is vacuum sealed and placed in a water bath circulating at a precise temperature. The food is cooked low and slow, resulting in perfectly cooked, delicious food.
This process has been used in professional kitchens for decades, but is now becoming more popular with home cooks as immersion circulators become more affordable.
An immersion circulator, on the other hand, is a device that is connected to a container of water and circulates hot water around the container to maintain a constant temperature. This is the device that is usually used in combination with the sous vide cooking method.
It is simpler to use than a sous vide machine because the container is smaller and easier to manage. The immersion circulator is more precise in controlling temperatures, as it can heat or cool the water to a precise degree.
In short, sous vide is the low and slow cooking method, while immersion circulators are the device used to heat and maintain a precise temperature for the sous vide cooking process.
Can you sous vide with Ziploc?

This can make the whole procedure difficult to fit into a busy lifestyle and not necessarily suitable for those who do not have the necessary time to properly and safely use the sous vide technique.
Thirdly, the cost of the necessary equipment can be quite high. A high-quality sous vide machine and a good thermometer are both expensive pieces of equipment, so significant investment will be required to produce optimal results with sous vide.
Finally, sous vide cooking can produce results that may not suit everyone’s taste. For example, some may find the texture of vacuum sealed food unpleasant and it is not suitable for quick-cooking methods such as stir-frying or pan-frying.
Therefore, it is not a cooking technique that will necessarily suit everybody.
Can I sous vide frozen steak?
Yes, you can sous vide frozen steak. This method of cooking works especially well with frozen steak because the low and slow cooking of sous vide helps to thaw and cook the steak without leaving it too tough or dry.
It’s important to note that most steak that you buy in the store has already been frozen to help preserve it, so unless it was a fresh steak, it’s likely that you are sous vide-ing a frozen steak. When cooking steak from a frozen state, it’s important to increase the cooking time to allow the steak to thaw and thoroughly cook before serving.
For example, if you are cooking a one-inch steak from a frozen state, you should set the sous vide to between 127-133°F (52. 7-56. 1°C) and cook for up to four hours or until it is cooked through.
Do sous vide bags leach chemicals?
No, sous vide bags do not typically leach chemicals into food. Sous vide cooking requires the use of special bags that are safe for food contact and are designed to be completely non-toxic and safe to use.
Many of the bags are made of polymers such as polyethylene or polypropylene that are free of BPA, BPS and phthalates. They are also designed to be resistant to punctures, tears, and heat and can withstand the high temperatures used in sous vide cooking.
These bags are also designed to be safe to use in direct contact with food, meaning that even if the bag does break down or degrade, there will be no chemicals or contaminants that leach into the food.
Do professional chefs use sous vide?
Yes, many professional chefs use sous vide techniques and equipment in their kitchens. Sous vide is a cooking method that involves vacuum sealing food into individual packets and cooking them in a precisely heated water bath.
By controlling the temperature of the water, chefs can keep the food in the ideal cooking state while retaining moisture and flavor. Sous vide cooking is especially popular for proteins like steaks, poultry, and fish, which are sometimes cooked for several hours for optimal tenderness and flavor.
Additionally, sous vide is a great way to prepare complex and delicate dishes like souffles and custards. Chefs also love sous vide for its convenience, as the food can be cooked in advance, held in the water bath until it is ready to be served, and quickly finished on the grill or with a torch.
What happens if a steak is in a sous vide too long?
If a steak is left in a sous vide machine for too long, the texture of the steak can become overly soft and mushy. When cooked with the sous vide method, the steak is gently cooked over an extended period of time, simmering in the center of the cut and slowly breaking down the proteins and fibers.
After an extended period of time, the steak will become too soft, resulting in a texture that is mushy rather than tender and juicy. Additionally, as flavor compounds break down, the steak can become overly flavorful and salty as seasonings are gradually broken down and released.
In short, it’s best to remove the steak from the sous vide machine as soon as it has finished cooking, to ensure that the steak is tender and juicy, with the perfect balance of flavor.
Does sous vide water need to circulate?
Yes, it is important that sous vide water circulates in order to ensure uniform cooking temperatures throughout the chamber. This is why sous vide machines typically have pumps that circulate the water.
The circulation also helps to keep even temperatures and prevents hot and cold spots throughout the device. Sous vide water must also be filtered to avoid bacteria growth, so the filter and pump are essential components of sous vide machines.
The circulating water helps to eliminate particles and bacteria, ensuring safe and properly cooked food.
