Various kinds of cakes

The history of cakes (蛋糕) is a fascinating journey from dense, bread-like honey loaves to the light, airy sponges we love today.

1. History and Origin (历史与起源)

• Ancient Beginnings: The word "cake" is of Viking origin (Old Norse "kaka"). The Ancient Egyptians were the first to show advanced baking skills, though their "cakes" were more like sweetened bread with honey, nuts, and dried fruits.
• The European Evolution: In the mid-17th century, Europe began using round molds and refined flour. However, these still relied on yeast and were very labor-intensive.
• The Industrial Revolution: The 19th century changed everything with the invention of baking powder and baking soda. This allowed cakes to rise without yeast, leading to the "sponge" texture we recognize today.
• 古代起源： “蛋糕”一词源于北欧维京语（kaka）。古埃及人是最早展示高超烘焙技术的民族，但当时的“蛋糕”更像是加入了蜂蜜、坚果和干果的甜面包。
• 欧洲演变： 17世纪中叶，欧洲开始使用圆形模具和精制面粉，但仍依赖酵母发酵，制作过程非常费力。
• 工业革命： 19世纪小苏打和泡打粉的发明彻底改变了烘焙史。这使得蛋糕不再依赖酵母也能蓬松，从而演变成了现代这种轻盈的质地。
