Due to Asia's vast size and extremely diverse geography and demographics, Asian cuisines are many and varied, and include East Asian cuisine, South Asian cuisine, Southeast Asian cuisine, Central Asian cuisine and West Asian cuisine. Ingredients common to East Asia and Southeast Asia (due to overseas Chinese influence) include rice, ginger, garlic, sesame seeds, chilies, dried onions, soy and tofu, with stir frying, steaming and deep frying being common cooking methods. While rice is common to most regional cuisines in Asia, different varieties are popular in the different regions: Basmati rice is popular in South Asia, Jasmine rice in Southeast Asia, and long-grain rice in China and short-grain rice in Japan and Korea. Curry is also a common ingredient found in South Asia, Southeast Asia and East Asia (notably Japanese curry); however, they are not popular in West Asian and Central Asian cuisines. Those curry dishes with origins in South Asia usually have a yogurt base, with origins in Southeast Asia a coconut milk base, and in East Asia a stewed meat and vegetable base. South Asian cuisine and Southeast Asian cuisine are often characterized by their extensive use of spices and herbs native to the tropical regions of Asia.
