Egg bread, also known as egg buns or gai daan jai in Cantonese, is a light, sweet, Chinese bakery product. The name “egg bread” or “egg bun” comes from the use of egg as a leavening agent in the dough, which gives the bread its distinctive taste and texture.
The Origin and History of Egg Bread
Egg bread originated in the Guangdong province of southern China. It became popular in Hong Kong and other areas due to the large population of Cantonese immigrants. The exact origins of the bread are uncertain, but some sources suggest it was invented in the 1940s or 1950s. The inexpensive ingredients and relatively simple preparation made it a staple food item in Hong Kong’s bakeries and cha chaan tengs (local diners).
As Cantonese migrants spread to North America, Australia, Europe and other parts of Asia, they brought their cuisine with them. This popularized Cantonese bakery items like pineapple buns, cocktail buns and egg bread around the world. Today, egg bread can be found in Chinatowns and Asian bakeries globally. However, it remains an iconic part of Hong Kong’s food culture.
The Unique Properties of Egg Bread
The distinct taste and texture of egg bread comes from its unique ingredients and cooking process. Instead of using yeast as the leavening agent, egg bread relies on the air beaten into egg whites. This gives the bread a fluffier, lighter and more cake-like texture compared to traditional yeast-leavened breads. The egg also adds color, richness, moisture and protein.
In addition to egg, the dough contains wheat flour, sugar, baking powder, milk powder and lard or butter. The well-beaten egg whites are gently folded into the other ingredients to keep the air bubbles intact. The dough is then baked in high heat to set the structure before the egg proteins coagulate and deflate. This creates the airy, cotton-soft crumb that egg bread is known for.
Egg bread has a pale yellow hue from the egg yolks. The crust is often soft with a slightly sweet flavor. The interior tend to be moist and light. These traits make egg bread well-suited for transforming into different shapes, consistencies and flavors.
Common Varieties and Fillings
Plain egg bread sometimes contains a few pieces of shredded coconut for added texture. But more often, various ingredients are added to the dough or used as fillings to create different varieties. Some popular types of egg bread include:
- Pineapple bun – topped with a sugar “cookie” crust
- Milk bread – made with evaporated milk for extra richness
- Cocktail bun – filled with coconut shreds
- Satay bun – filled with spicy peanut crumbs
- Hot dog bun – shaped like a hot dog and filled with sausage
Other common fillings and mix-ins include red bean paste, custard, taro, ham, chicken, and shredded pork. The dough’s mildly sweet flavor complements both savory and sweet fillings. Egg bread is commonly shaped into round buns, but can also be made into loaves, twists and other shapes.
The Role of Egg in Egg Bread
So why is it called egg bread? The egg serves multiple essential functions:
- Leavening – The beaten egg whites create air bubbles that cause the bread to rise.
- Binding – Eggs help bind the ingredients together into a cohesive dough.
- Texture – Air bubbles from the egg whites give a fluffy, tender crumb.
- Color – Egg yolks provide a pale yellow hue.
- Flavor – Eggs provide a rich taste and aroma.
- Nutrition – Eggs add protein, vitamins and minerals.
Without egg, this bread would be much denser and drier, with a very different texture. The egg is integral both for the taste and the rise. So it is truly the key ingredient that makes egg bread “egg bread”.
The Egg Bread Making Process
Making egg bread involves a simple straight dough method. The main steps are:
- Beat egg whites until frothy and airy.
- In a separate bowl, mix flour, sugar, milk powder and lard/butter.
- Gently fold the beaten egg whites into the dry mixture.
- Knead briefly until a smooth dough forms.
- For filled egg bread, roll out dough and add fillings before shaping.
- Proof the dough for 30-60 minutes until puffy.
- Bake in a 375°F oven for 15-25 minutes.
- Brush hot bread with syrup, milk or egg wash.
Kneading is kept very minimal to prevent deflating the delicate egg-leavened dough. Resting and proofing the dough allows the egg bubbles to expand and lift the bread. Brushing the hot bread keeps the crust and crumb soft.
