Mee siam
Mee siam is a dish of thin rice vermicelli of hot, sweet and sour flavours, originating in Penang but popular among the Malay and Peranakan communities throughout Peninsular Malaysia and Singapore, although the dish is called "Siamese noodle" in Malay and thus appears to be inspired by or adapted from Thai flavours when Thailand was formerly known as Siam. Mee siam is related to kerabu bee hoon although there is a significant difference between the recipes. According to Wendy Hutton, due to the Thai influence on Northern Malaysian cuisine, it is believed that the dish originates from Penang, where Thai influences on Malay and Peranakan dishes are common. Dishes from Penang possess Thai influences, such as more liberal use of tamarind and other sour ingredients including dishes like mee siam and asam laksa.
