Comparison Tefal OptiGrill GC7P0810 black vs De'Longhi CGH920 stainless steel

The maximum heating temperature of the electric grill panels supported by the device in normal operation. It is desirable that its optimal indicator is about 230 — 240 ° C. Electric grills with such a heating temperature threshold will be able to fry any food with high quality. A high temperature may only be needed for some specific types of cooking, and a lower temperature will not ensure proper grilling for home use.

Electric grill control panel design.

— Control knob. Mechanical control is carried out using rotary knobs and switches. Most parameters in such devices are set and controlled manually. In this case, the control elements are connected to the working parts of the electric grill directly, without additional electronic circuits. This option is simple, reliable and low cost; however, it is only suitable for the most basic functions, but electric grills usually do not require more.

– Push-button. Push-button control is based on electronic circuits. Such systems are more accurate than mechanical ones (for example, the timer in such electric grills can usually be set with an accuracy of up to a few seconds), and more options and modes are provided. On the other hand, such control is more complex and more expensive than mechanical control.

– Touch. A type of electronic control with touch switches. Compared to push-button models, it provides a high level of comfort in operation, and looks more modern and aesthetically pleasing. Touch control is found mainly in top models of electric grills.

The size of the work surface installed in the grill — that is, the surface intended for the cooked products.

The amount of food that can be cooked directly depends on this indicator at a time. On the other hand, a large work surface requires high power, and also directly affects the overall dimensions of the grill. Therefore, when choosing according to this indicator, it is necessary to take into account the expected volumes of cooking and the amount of space available for installing the device first of all.

Note that this parameter is indicated by the length and width of the working surface, regardless of its shape. Therefore, the same dimensions — for example, 30x30 cm — can mean both a square and a round device, while the usable area in the first case will be noticeably larger than in the second. So in such cases, it will not prevent clarify the specific shape of the working surface.

The shape that the working surface of the grill has.

— Corrugated. Corrugated plates with a striped surface are designed in a way that only the protruding ribs come into contact with the product, allowing fat and juice to flow freely into the recesses. The heat of the grill causes the liquid in the recesses to boil, creating distinctive fried stripes on the dish. The surface between the stripes is not fried as much as it is sealed. This corrugated surface is considered ideal for cooking meat as it allows excess fat to drip off, resulting in a less greasy finished dish compared to using a smooth surface. However, vegetables are not as well-suited for a corrugated grill.

— Smooth. The smooth surface, without any prominent texture, is typically considered ideal for frying vegetables, but it is not as effective for cooking meat. On a smooth surface, meat tends to fry in its own juice, resulting in a dish that is higher in fat compared to using a ribbed surface.

— Smooth and corrugated. Some grills are designed or come with a set of surfaces that offer both types of textures mentioned earlier. This includes a combination of smooth and corrugated surfaces. This design is commonly found in barbecue grills and raclette grills, allowing users to cook different types of food simultaneously. Another option, commonly seen in...contact grills, involves interchangeable plates that come with the device. These plates can be adjusted to accommodate specific foods. Additionally, in models that offer a 180° opening function, different types of dishes can be cooked simultaneously, similar to an open combination grill.

— Grid. The working surface of the grill is typically in the form of a grid positioned above the heater. One of the main advantages of this design is its ability to impart a smoky flavor to dishes. The juice and fat from the food being cooked drip onto the heater, evaporating and infusing the dish with a distinct aroma. However, these grills require regular maintenance and cleaning, not only of the grid but also of the heater. The cleaning process can be challenging due to the presence of hard-to-reach areas. As a result, this type of grill has become quite rare in modern times.

Additional features of the electric grill.

Features such as thermostat, off timer and < a href="/list/43/pr-21604/">auto-cooking, can be found in all types of grills (see “Type”); removable plates are also very popular, they are not found except in electric frying pans; and here is fixing the height of the top plate, opening 180° and separate temperature control are relevant mainly for pressure grills (with rare exceptions). Here's a more detailed description of each of these features:

— Thermostat. Regulator that allows to automatically maintain the set temperature of the working surface. To do this, a special sensor monitors the temperature of the grill, turning off the heating when it reaches the desired value and turning it on again when it cools down by a few degrees. This allows to maintain the required cooking mode without any extra effort. Thermostats are very simple in design and inexpensive, and therefore are found in most modern electric grills.

— Timer. The timer that turns off the heating after a specified time. This feature saves the user from having to keep track of time: it is enough to set the desired value on the timer. Among other things, due to this, the risk of overcooking or “burning” the cooked dish is s...ignificantly reduced: such a nuisance can only occur if too much time was chosen for cooking. Note that the capabilities of the timer depend on the type of control (see "Control"): with mechanical control, the time, usually, is set quite approximately (sometimes with an accuracy of up to a minute or two), with electronic control — with an accuracy of up to a second.

— Autocook. The presence of auto-cooking programs in the grill — one or more. This feature differs from the timer described above in greater convenience and functionality. So, the user does not need to manually set the grill temperature for the operating time — usually, it is enough to select the type of product and the desired degree of roasting/warming up. A specific set of auto-cooking programs may be different, it should be specified separately; among the most popular options are “meat” (often with a choice of degree of roasting), “poultry”, “fish”, “burgers”, “sandwiches”, “sausages”, as well as a defrost mode.

— Removable plates. Possibility to remove the grill plate(s). The main purpose of this function is to make it easier to wash and clean the work surface after use. So, removable plates can be washed without problems in a kitchen sink, and often even in a dishwasher, while such features are not available for a non-removable design. In addition, some devices with this feature can be equipped with interchangeable plates of different types (see "Plates included"); and if the removable plate is damaged, it is enough to buy a similar part for a replacement — you do not need to change the entire grill or take it to repair.

— Plate height auto-adjustment. In grills with this feature, the top plate is mounted on a special hinge, which allows it to automatically adjust to the height of the food to be cooked. In this case, you do not need to make any additional settings — just lower the lid, and it, clinging to the contents, will itself take the optimal position. This height auto-adjustment differs from another similar function — manual height adjustment (see below). The disadvantages of this design, compared with the manual height adjustment, include the fact that the top plate must necessarily be in contact with the contents, there is no possibility to heat the products from above in a "non-contact" way. However, this moment is not so often critical; in addition, there are a fairly large number of models where the hinge is combined with manual adjustment.

— Fixation of the height of the plates. Possibility to manually adjust the height of the top plate. The user can select the position of the plate below which it should not fall. This complicates the setup somewhat, but provides some advantages and additional capabilities. First of all, this is the possibility of “contactless” cooking - when the top plate is not adjacent to the food, and heating from above occurs only due to thermal radiation.

— Opening 180°. A feature found primarily in contact pressure grills, as well as individual pizza makers (see “Type”). When the lid is opened 180 degrees, such a device actually turns into a barbecue grill with two separate working surfaces. Thus, this feature allows you to grill not only in a “closed” but also in an “open” way. And some similar models provide separate temperature control (see below), further expanding the functionality.

— Separate temperature control. In grills with this feature, the work surface is divided into two parts, and the temperature of each of them can be adjusted independently of the other. Most of these models are contact grills with the ability to open at 180° (see above) — they can separately adjust the temperature of the main surface and the lid. In the "open" format of work, this allows you to simultaneously cook dishes that require different temperature conditions; and when the grill is closed, due to separate adjustment, it is possible to provide different intensity of processing from above and below — for example, to brown the bottom half of the burger and only slightly heat the top. There are also open grills, in which the working surface is divided into two independent temperature zones; however, this possibility significantly complicates the design and increases its cost, so that very few such models are produced.

The presence of its own display in the design of the grill.

This function is found only in advanced models with electronic control (see "Control"). At the same time, both relatively simple and quite advanced displays can be installed in modern grills, in some models even colour ones. However, such equipment makes working with the grill more convenient and visual anyway: various useful data can be displayed on the screen (timer settings, selected temperature mode or programme, time until the end of cooking, etc.). Models with this function are expensive, but this is not due to the presence of a screen, but to the extensive functionality in general — there is no need to use displays in simpler devices.

The length of the cable for connecting to the network provided in the design of the device.

It is worth considering the estimated distance to the outlet when choosing according to this indicator: a wire that is too short will not reach it, too long will get mixed up and create inconvenience. At the same time, also note that most electric grills are designed for use at home and other similar conditions, where there are no particular problems with access to sockets. Therefore, the cable length in such devices does not exceed 2 m, and in some models it is even about 80 cm.
