I made something familiar in the supermarket and pasar malam (night market) back home. Usually sold for $1 each and it comes in fish balls, cutterfish balls and shrimp balls.
This snack is super easy to make. Just buy a package of DoDo cutterfish balls (of course you can choose any variety you like), thaw it until soft and deep-fry it in medium hot oil until golden brown. Skewer them into a satay stick and serve with Thai sweet chilli sauce. Kids friendly as well.
