A favourite breakfast accompaniment of mine are pa ton go, Chinese-style doughnuts.
They are widely available across Southeast Asia from the Chinese vendors and are often sold with soybean milk.
I consider them essential when drinking the rich local coffee, overly sweetened with condensed milk. Tear a pa ton go in half and dip the little fella in your coffee and it is a match made in heaven.
In Vientiane they are known as kanom jap gluay and many noodle shops have a plate of them on the table so you can help yourself.
