Kuih talam is the two tone one, a salty thick coconut top over a sweet green pandan or gula melaka base. That contrast is the whole appeal. The thick santan top is the fat driver and the sweet base is the carbs, landing a piece around 130 calories.
The ubi kayu (tapioca) and keladi (taro) versions are a bit heavier, around 150 to 170, because the dense starch replaces water. Still treat territory. One piece, enjoy it, move on.
