diós

Diós is the Hungarian adjective meaning walnut-flavored or containing walnuts. It is formed from dió, the word for walnut, with the adjectival suffix -s, and is used to indicate that a dish includes walnuts or tastes of walnut.

In culinary Hungarian, diós appears in the names of desserts and sauces. Classic preparations include diós torta (walnut cake), diós bejgli (walnut pastry roll), diós rétes (walnut strudel), and diós tészta (pasta with walnut filling or sauce). The term can also describe ingredients in recipes such as diós krém (walnut cream) or diós szósz (walnut sauce).

Botanically and nutritionally, the nuts used are typically walnuts from Juglans regia, cultivated across Hungary and Central Europe. Walnuts are rich in fats, especially unsaturated fats, and provide protein, fiber, and minerals such as magnesium. They are a common allergen and should be stored in a cool, dry place; refrigerating or freezing can extend shelf life. Diós-flavored dishes are common in traditional Hungarian pastries and regional specialties, reflecting the long-standing use of walnuts in Central European cuisine.
