Krathong thong is a traditional appetizer consisting of pastry cups that are filled with various ingredients. In Thailand, to make the pastry shells, cooks use a special mold that looks like a cupcake pan at the end of a long handle. The pastry cups are usually made with a combination of plain and rice flour, salt, sugar, egg yolks, water, mineral water, and oil.

The ingredients for the filling vary, and some of the popular ones include pork or chicken, onions, carrots, potatoes, curry powder, and garlic. These golden cups are available in numerous eateries and at street food stands in Thailand.
