Abacus Seeds (算盘子, suan pan zi) is a Hakka dish you'll find at Hakka restaurants and some heritage kopitiam spots across Malaysia, especially in KL, Bentong and parts of Sabah. If you've never had it, the dough beads are made from yam and tapioca starch, then hand-rolled into little round shapes that look like abacus beads, boiled and stir-fried with minced pork, dried shrimp, shiitake mushrooms and black fungus. The texture is QQ and slightly sticky, think a chewier version of mochi but savory. At 520 calories a plate it's not a diet food, but it's also not a disaster. The yam dough beads alone account for 290 of those calories, and the minced pork adds another 145. To be straight with you though, this is a medium-confidence estimate because proper lab-tested nutrition data for Abacus Seeds is basically nonexistent. Take the number as a useful guide, not gospel.
What actually moves the number is how heavy-handed the wok is with oil and how big the portion is. A generous cook who doubles the oil can easily add 80 to 100 extra calories without you noticing. Portion size is the other big lever: a smaller serve of 200g instead of 320g would drop you closer to 325 calories. The minced pork contributes real protein but also fat, so if you could swap in lean chicken mince you'd save maybe 30 to 40 calories. Ask for less oil if you're ordering at a restaurant, most places will accommodate. The dried shrimp and mushrooms are practically free at only 40 calories for 30g, so don't stress about those.
