Today, I made a lovely round bread with "growth rings" on it. In Hong Kong, we call it "wheel bread"(車輪包）. When I was a kid, I was often responsible for buying freshly baked "wheel bread" for my family from a nearby bakery. Back then, the wheel bread was either plain or with raisins. For a child, it smelled delicious no matter which flavor. Sometimes I couldn't help but started nibbling it on the way home.
Today, decades later, the "wheel bread" has become less popular in Hong Kong. However, to my surprise, it still appears on the menu of Japanese bakeries. In addition to the "original" flavor, the unique Japanese matcha-red bean combination is also a popular choice. Some bakeries such as Moashikisaikan use wormwood for coloring.
Since I didn't have wormwood, I used matcha powder for coloring and replaced 5% of the flour in the formula with CLAS.
Cutey "wheel bread" brings back childhood memories.
It's made in this heavy-duty mold.
My mom sent it to me from Hong Kong. The shipping was super expensive. Fortunately, you can buy it online now, or if you are in Canada, you can check with this store in Toronto. This store is a branch of a well-known Hong Kong cutlery/baking equipment company. It's a fun place to visit. I shop there every time I am in Hong Kong.
