Dodol is that sticky, dark, chewy sweet cooked down for hours from glutinous rice flour, coconut milk and gula melaka until it is almost solid. Because all the water is cooked out, it is one of the most calorie dense kuih per gram, around 350 calories per 100g. The pieces are small though, so one is around 100 calories.
The durian version is richer, a bit higher from the durian fat. Dodol is a proper concentrated sweet, so a small piece goes a long way. The trap is it keeps well and sits around the house during festive season, so you nibble piece after piece.
