Serradura
Serradura , also known as sawdust pudding or Macau pudding, is a well-known Portuguese dessert, popular in both Portugal and Macau (a former Portuguese colony in China), as well as Goa (a former Portuguese colony in India), with a layered appearance alternating between whipped cream and crumbled Marie biscuit. The name serradura is a Portuguese word for “sawdust”, which refers to the way the biscuits look in the pudding, as they are crushed very fine into crumbs. Serradura is a dessert originated in Portugal, which became famous in Macau. It is a very common dessert that can be easily found in different restaurants and bakeries in Macau, which is why Serradura is chosen as one of the must-try foods of Macau.
