The taro paste filling of Century Cafe's taro buns is off the charts. It is a medium purple color (which I like because purple foods are hard to find). I'm guessing the taro paste filling is made by cooking the taro and mashing it with butter and sugar. It's probably a secret recipe, but as far as I can taste, those are the key ingredients. The texture of the paste is smooth, and the flavor is 100% taro. From time to time you can find stray chunks of tasty taro within the paste, making the experience even more delicious.
The soft bread of the bun, combined with the flaky egg topping and the buttery taro paste filling make this bun my favorite. It sells for 70 cents, which most of the cafe's other basic buns also sell for. It is best eaten when warm and fresh, but can also be kept for a couple of days and reheated in the microwave.
