Asian Bakery Style Frankfurt and Corn Salad Soft Roll
Updated: Mar 8, 2022

These buns are popular in Asian Bakeries and it often enjoyed for breakfast or lunch. Frankfurt is just one of the many things you can use as topping as you can pretty much put anything savoury or sweet on top.
The bread itself is made from my own Tang Zhong bread recipe and it is always my preferred for any soft roll, although I have different variations for a similar recipe that uses whole wheat or other flours as well, and if you are interested, check out my post on Whole Wheat Shokupan.
Tang Zhong bread uses a different method of bread making very similar to the European bread that uses poolish or biga. Although poolish and biga are made by mixing water and flour with a small amount of yeast and leave to pre ferment for several hours to a day, the Tang Zhong Method is much more straight forward and less time consuming. Poolish and Biga are also often used in European Bread to enhance flavour but the Tang Zhong Method is predominantly utilised in Asian bread for the soft texture.
Tang Zhong
When making bread with the Tang Zhong method, a small portion of the flour and liquid (milk/water) are heated and whisked over a heat source until the starch in the flour starts to absorb all of the liquid and turns to a thick sticky mass. This chemical changes in the starch is called "swelling". When starch in the wheat flour absorbs liquid through heat, it starts to swell and thicken and are non reversible. This substance is called "Tang Zhong". The ratio for Tang Zhong is always 1:5, with 1 part flour and 5 parts liquid. The flour quantity of the Tang Zhong is usually around 8-10% extraction from the flour quantity as a whole.
This retention of water is what creates a soft and moist bread that does not dry overnight like most bread recipe. I have tried leaving some of the baked bread over a week that was kept at room temperature and wrap tight in cling film. The texture was just like from the first day it was baked. This always fascinates me.
