I heard these sweets are popular in Vietnam. They are easy to make, as you just combine pancake mix with a couple of ingredients and deep fry.
I saw these Vietnamese sweets in a cooking book once. I thought I could probably recreate it using pancake mix to make a thick batter that would taste delicious when fried.
You have to mix the pancake mix until it is thick and smooth. Otherwise, the nozzle will become blocked with small lumps!
