What is sous vide and why it’s worth trying

Sous vide is a cooking method in a vacuum-sealed bag at a precisely controlled low temperature. The result is meat that is evenly cooked throughout its cross-section – no dry edges and raw center. Foods retain their juiciness, nutrients, and flavor because they are not cooked directly in water. And since the temperature is constant, it is impossible to overcook or burn the food.

Practically, it works by seasoning the meat (or vegetables), vacuum-sealing it, and placing it in water heated to a precise temperature – for example, 55 °C for a medium-rare steak. The cooker maintains a stable temperature for several hours. After removal, simply sear the meat briefly in a pan or on a grill to get a crust.

What the Siguro Tenderino can do

The Tenderino is an immersion cooker with a power output of 850 W, which you attach with a clamp to a pot or container. The temperature range is 10–95 °C with an accuracy of ±0.5 °C. The maximum cooking time is almost 100 hours, so you can handle long preparations (such as pulled pork). The cooker is water-resistant according to the IPX7 standard, so you don’t have to worry about splashing water.

Control is via a touch panel with a backlit display or via the TUYA app (iOS/Android). Via WiFi or Bluetooth, you can set the temperature, time, and delayed start, and monitor the cooking progress from the couch. The app also includes recipes for inspiration.

Practical side: what you’ll need

The cooker alone is not enough – you will need a vacuum sealer with bags or foils (Siguro offers them from 199 CZK) and a sufficiently tall container. The manufacturer recommends a pot with a volume of 6–13 liters and a minimum depth of 15 cm. Regular household pots may not be sufficient – many users recommend purchasing a special sous vide container with a lid (from 589 CZK), which insulates better and maintains temperature.

The mounting clamp has a maximum span of 33 mm, so some thick-walled pots or pressure cookers with a rim may not fit. The cable is 1 meter long, which is sufficient for most kitchens. The cooker itself is compact and easy to store after use.

What users say

On Alza, the Siguro Tenderino has a rating of 4.6 out of 5 from 157 customers. 93% of buyers recommend the product, over 5,000 units have been sold, and the return rate is low (2.55%). Users most often praise its quiet operation, reliable temperature maintenance, and app connectivity. One reviewer wrote that sous vide “opened up a whole new dimension of cooking” for him and his steaks are now always perfect.

Critical voices are mainly directed at the TUYA app: it is functional but not perfect. It cannot reliably save custom recipes, and some users report occasional WiFi outages. Setting the temperature and time directly on the cooker is, according to reviews, “fiddly” – either you switch by tenths, or the values jump. Several users mention that the cooker is larger than they expected and they needed to buy a taller container. And occasionally, there is a complaint about whistling after prolonged use.

When it doesn’t make sense

If you mainly cook quick meals and don’t have time for longer preparation (a sous vide steak takes 1–2 hours), this method won’t suit you. Also, if you don’t have a vacuum sealer and don’t want to invest another approximately 1,500 CZK in one, you’ll stick to classic cooking. And if you expect a flawless smart app on the level of premium brands, you’ll probably be disappointed – TUYA is functional, but basic.

Verdict: who it’s worth it for

The Siguro Tenderino for 1,599 CZK is a solid entry into the world of sous vide cooking. You get WiFi and Bluetooth connectivity, a 3-year warranty with the option of immediate replacement, and a cooker that reliably maintains temperature. For those who want to prepare restaurant-quality steaks, chicken breasts, or vegetables at home, it’s one of the most affordable ways to start. However, be aware that you will need a vacuum sealer and a suitable container – the cooker itself is only part of the equation.
