Meanwhile, the basic characteristic taste of Thai food in different parts of the country can be described in different ways: in the central region, food is hot, salty, sweet and sour. Rice is served with different types of nam phrik and soups e.g. tom yam kung (prawn soup with lemon grass. Dishes usually contain a lot of condiments and spices. In the North, food is mild or hot, salty and sour, but never sweet. Sticky rice is served with boiled vegetables, nam phrik oong and soups or curries. The North is also well-known for its sausage called "naem" which consists of fermented minced pork. It has a sour flavour and is sold wrapped in cellophane and banana leaf.
