Soy milk is a popular and nutritious drink that can be found in Taichung. It is made by soaking and grinding soybeans, then boiling the mixture and straining out the solids. The resulting liquid is a creamy and plant-based alternative to dairy milk. Soy milk can be enjoyed hot or cold and is often served with breakfast or as a refreshing beverage throughout the day. It can also be flavored with ingredients like black sesame or almond for added variety.
