What chocolate is known as fat from the north?

This nickname comes from the high cocoa butter content in couverture chocolate, which gives it a luxurious, smooth, and melt-in-your-mouth texture. This rich, velvety feel is sometimes described as a "fatty" texture, hence the nickname.

"North" refers to the fact that most couverture chocolate is produced in countries in the northern hemisphere, such as Switzerland, France, and Belgium.

However, it's important to note that this nickname is informal and not widely used. Most people simply refer to it as couverture chocolate.
