Soboro
Soboro-ppang , or gombo-ppang (곰보빵; standard language), often translated as soboro bread, soboro pastry, or soboro bun, and also known as Korean streusel bread, is a sweet bun with a streusel-like upper crust popular in Korea. The bun is made of flour, sugar, eggs, and dough and baked with a crisp, bumpy surface on top. The word "soboro" is a Japanese word which refers to the streusel topping of the bun, which is often made with peanut butter as a key ingredient. Soboro refers to fried and minced meat or fish in Japanese, which resembles the streusel on top of the bread.
