tojáshéjak

tojáshéjak refers to eggshells in Hungarian. These are the outer protective coverings of bird eggs, primarily known from domestic fowl like chickens, but also from other birds. Eggshells are composed mainly of calcium carbonate, with smaller amounts of other minerals and organic matter. Their primary function is to protect the developing embryo inside the egg from physical damage and microbial contamination.

In culinary contexts, eggshells are generally discarded as waste. However, they have found various uses beyond food preparation. Historically and in some traditional practices, finely ground eggshells have been used as a source of calcium. This practice has seen a resurgence in some circles as a natural dietary supplement. It's important to note that raw eggshells can harbor bacteria like Salmonella, so any intended consumption requires thorough cleaning and sterilization.

Beyond nutritional applications, eggshells are utilized in crafts and gardening. Their distinctive texture and color make them suitable for decorative purposes, mosaics, and various art projects. In gardening, crushed eggshells are sometimes added to soil as a natural fertilizer, providing calcium which can benefit plant health, particularly in preventing blossom end rot in some vegetables. They can also act as a deterrent to certain garden pests. The ease of availability and natural composition of eggshells contribute to their diverse applications.
