I first learned about gold leaf at work. It was used as a sprinkle to decorate confectionery. Such a small element drastically changed the look of sweets. We decided to try leaf decoration, which is also easy to work with. Such desserts cost more, but they go down a treat.
Being interested in the novelties of the industry, it became clear that gold decor has become a trend of our time. I also wanted to try it. At first we used exclusively fine gold, and gradually became acquainted with sheets as well. The right product helps to create a unique eye-catching sweetness, as well as giving dishes a rich appearance.
To attract attention to your own products, you often have to experiment. Few people are surprised by chocolate figurines anymore. Gold elements added to products do not weigh them down, but rather make a festive accent. Gold in any form is comfortable to work with, and the appearance of products changes instantly.
It must be said that the material is completely safe for health and is not capable of provoking allergic reactions. The absence of taste and smell is not able to change the taste of food, which is also important. With gold, you can make inscriptions, drawings or put an image. In any case, the dishes look festive and unusual.
