This is probably one of the few available biscuits when I was small. Most kids will eat the sugar and throw the biscuit part away. My kids are still doing that, leaving a bag of saliva soaked biscuits which will be fed to the monkeys later on.
There are a few shops in Penang which exclusively sell only biscuits. A little like those snack stations in hypermarkets. But the difference is the service. The shopkeeper will describe to you the taste of every type of biscuit, recommending the freshest stock and let you sample all you want. However, the downside is the amount you buy. They have this old weighing scale unlike those digital ones and therefore, everything you buy must be minimum 200gm – 300 gm or it will be too light for their weighing scale.
