Shandong is a large peninsula surrounded by the sea, with the Yellow River meandering through the center. As a result, seafood is a major component of Shandong cuisine. Shandong's most famous dish is the "sweet and sour carp". A truly authentic "sweet and sour carp" must come from the Yellow River.
Shangdong cuisine is famous for its wide selection of material and use of different cooking methods. The raw materials are mainly domestic animals and birds, seafood and vegetables. The masterly cooking techniques include Bao (quick frying), Liu (quick frying with corn flour), Pa (stewing), roasting, boiling, using sugar to make fruit, crystallizing with honey.

Condiments such as sauce paste, fistulous onion and garlic are freely used, so Shangdong dishes usually taste pungent. Soups are given much emphasis in Shangdong dishes. Clear soup (or thin soup) features clear and fresh while milk soup (or creamy soup) looks thick and tastes strong, both of which are often choicely made to add freshness to the dishes. The dishes are mainly clear, fresh and fatty, perfect with Shandong's own famous beer, Qingdao Beer.
In addition to sweet and sour carp, typical courses in Shandong cuisine include braised abalone with shells, fried sea cucumber with fistulous onion, fragrant calamus in milk soup, quick-fried double fats (a very traditional Shandong dish consisting of pork tripe and chicken gizzards), and Dezhou stewed chicken. Dezhou stewed chicken is known throughout the country; the chicken is so well cooked that the meat easily separates from the bone although the shape of the chicken is preserved.
