When we cook, we often perform many activities automatically, which leads to repeating the same mistakes over and over again. We want our dishes to be not only delicious, but also nutritious. Find out what mistakes are most commonly made in the kitchen and try to avoid them. A few simple rules will help you keep the kitchen in order and make the most out of the ingredients you use.
01 / 07
One cutting platter
Unfortunately, this is the most commonly made mistake in the kitchen. Even if we have multiple cutting boards, they are used for all kinds of products. In every kitchen, there should be cutting boards specifically for meat and separate ones for the rest of the products. Raw meat can contain bacteria and parasites that are dangerous to health, so it's important to avoid contact with other products. It's a good idea if the cutting board for meat is made of glass or plastic. Wood absorbs the juices that come out of the meat, making wooden cutting boards harder to clean. Inadequate cleaning can lead to bacterial growth and food poisoning.

Storage of olive oil in transparent containers
Oil is a highly valuable fat that contains a vast number of mineral ingredients and vitamins. Therefore, it is crucial to effectively protect it from excessive light exposure. Storing oil in a transparent container in a well-lit location results in the oil losing its valuable health properties. The best solution is to store oil in dark containers in a cool room with minimal light access. It is also important to avoid excessively low temperatures, hence a cabinet is a better choice than a refrigerator shelf. Oil that is stored at a temperature below 8 degrees becomes cloudy and loses its flavor. On store shelves, one can find oil in transparent containers, but it is better to choose those whose container is dark to ensure that one is selecting oil of higher quality.

Butter Preservation
Similar to oil, butter requires appropriate storage conditions due to its short shelf life as an animal fat. Butter quickly undergoes a digestive process, rendering it unfit for consumption after a few days. It is important to store butter in a cool and dark place to prevent its degradation. The best solution is to store butter in the refrigerator in an opaque container to avoid contact with oxygen and light. Light and oxygen cause the formation of oxygen in a fat, which is harmful to the health of oxycholesterols.

Tomatoes in the refrigerator
Tomatoes are highly sensitive to low temperatures and therefore should not be stored in cold environments as they lose their natural taste and aroma. Like all fruits and vegetables, tomatoes release large amounts of ethylene, a plant hormone responsible for their ripening. Storing tomatoes near other vegetables, especially fruits, can cause them to ripen and spoil faster.
05 / 07
Excessive removal of skins from fruits and vegetables
There is no debate that every fruit or vegetable should be cleaned before consumption. Bacteria present on them can cause dangerous diseases, even fatal parasites. Many fruits and vegetables also need to be peeled before eating. However, most fruits and vegetables have a skin that is edible.
06 / 07
Preparation of legume plants
Legume plants, such as beans, require adequate soaking in water before consumption. They are rich in protein and other nutritional properties. They also contain lectins that inhibit the release of trypsin, a digestive protein enzyme. A lack of trypsin leads to the development of intestinal bacteria, resulting in strong, often painful bloating. Legume plants also contain stachiozene and raffinose, hard-to-digest complex sugars whose enzymes are produced by the human body cannot be digested either. The decomposition of these sugars results in the formation of carbon dioxide and hydrogen, which are responsible for the formation of gases. Water rinses out the compounds from the legume plants that cause these discomforts, but it also deprives them of vitamins and minerals. To reduce the discomfort of digestive problems after consuming legume plants, digestion-enhancing herbs can be used.

Preparation of potatoes in sour soup
When we plan to prepare a potato soup or a sauerkraut soup with potatoes, we must remember that there are two ways we can do it. The first method is to cook the potatoes first in lightly salted water and then add an acidic ingredient such as pickled cucumbers or sauerkraut. The potatoes should only be added to the soup when they are done. The second method is to cook the potatoes in a separate pot and then add them to the soup only when the potatoes are almost done. In both cases, the potatoes should not be added to the soup too soon, as they will remain hard and glassy even after hours of cooking. If we follow one of these methods, we can avoid a culinary disaster.
