Roti Tisu is that comically tall cone-shaped roti you see at mamak stalls, stretched so thin it turns golden and crispy, then stood upright on a plate and hit with sugar and condensed milk. It looks like a party trick, and honestly it is one. At 750 calories a cone, it is built for sharing, full stop. The calorie math here is mostly fat and carbs: 300 calories from ghee alone, 93g of carbs, and only 11g of protein. There is almost nothing keeping you full. It is a crowd-pleaser, great for a table of six splitting one, terrible idea if you are eating it solo and trying to lose weight. Fair warning: these numbers are a ballpark estimate because hard data for Roti Tisu is thin. Different mamak stalls use wildly different amounts of ghee and condensed milk, so the real number could be anywhere from 650 to 850 calories depending on who is making it.
What actually swings the number is how heavy-handed they are with the condensed milk drizzle. Skip it and you drop from 750 to about 670 calories. Ask for less sugar and you shave a bit more. The plain version with sugar only is still not a diet food, but it is 80 calories lighter than the full load. The ice cream version at some kopitiam hits 950 calories for one cone, which is basically two meals for a person on a deficit. If you are at a mamak table and someone orders one, just have a piece or two and move on. The problem is nobody treats it like a sharing dish when they are hungry lah.
