What's the difference between a latte and a dancing latte

There's a big difference.

Latte is a derivative of espresso, which is generally made by pouring 1 cup of espresso and 4 cups of espresso, then pour the hot milk, close to full, and finally pour the foam. The taste is mellow, the smell of milk is heavy and the taste is silky.

The dancing latte is made by a mocha pot. (I think the siphon pot is fine). The order of making the dancing latte is also different. The dancing latte is made with milk first, followed by coffee, and it is made by Cold Milk. In this way, the hot coffee will have a "dancing" effect due to cold and hot convection.
