Kuih keria is the sweet potato doughnut ring with that crackly hard gula melaka glaze. The sweet potato itself is fairly low calorie, so the calories come from two places: the deep frying and the sugar coat. One ring is around 95 calories, which honestly is not bad for how satisfying it is.
The glaze is the swing factor. A generously coated, oil heavy street piece can hit 130 plus. A plain sugar dusted one is lighter at around 80. As doughnut style treats go, it is on the reasonable end, but it is still a treat.
