I'm guessing South African Chinese decided to translate "dan san" (蛋散) to "bow ties" because they look like bow ties. They are amazingly good, at least the ones my mom and grandmother made. The ones at bakeries are greasy or the dough is too thick so I no longer buy even if I'm craving them.
Anyways let me introduce you to my family's bow ties. They are light pastries that are deep fried and covered with a syrup coating. They are shaped into bow ties, hence the name bow ties.
The dough is simple to make. It's just sifted flour and baking powder. You can use vegetable oil but my mom said lard makes the dough more crispy and flaky.
Then four eggs are added.
