Spinach also called “SiGeumChi (시금치) is a green-yellow leafy vegetable that contains a large number of various nutrients such as vitamins, iron, and dietary fiber. Spinach has strong cold resistance, so it grows well in cool spring, autumn, and winter. Spinach harvested at this time contains more vitamin C. Spinach is divided into Eastern and Western varieties. Eastern varieties are resistant to cold, so they are cultivated in autumn and winter and are called winter spinach, while Western varieties are cultivated in spring and summer and are called summer spinach. Winter spinach leaves are sharp, but summer spinach leaves are thick and round. In the West, young spinach leaves are mainly used for salads. In Korea, spinach is boiled in soybean paste soup and eaten, but in general, it is often eaten as a side dish for vegetables by blanching it and mixing it with sesame oil and minced seasoning.
