These are *patongo*, Thai-style deep-fried dough sticks, often eaten for breakfast with coffee, soymilk, or sometimes with the green pandan custard (*sangkhaya bai toey*) you have. The soy milk (*nam tao hoo*) is also a common breakfast drink. The peanuts are an interesting accompaniment, perhaps for a savory contrast. *Patongo* are believed to have originated from Chinese *youtiao* but have evolved with local Thai tastes.
