Different tastes. Double-skin milk has a stronger fragrance, and the skin is obviously layered when eating, and the taste is smooth and delicious. However, pudding is actually single-skinned milk, and some even have no milk skin. The method is simple. You only need to add milk and eggs to flour and vegetable starch to increase its consistency. It tastes like jelly. However, the jelly is only semi-solidified, and the milk flavor is not as rich as double-skin milk.
Different places of origin. Pudding and double-skin milk come from different producing areas except for the differences in practice and taste. Pudding originated in Britain, and it is called "pudding" in Britain, which belongs to foreign products, while double-skin milk is an out-and-out domestic product, which was first born in Guangdong. So if you want to eat authentic double-skin milk, you still have to go to Guangzhou, Guangdong, where the taste is the purest.
