What is cocoa butter and what is it used for?

It's the fat from the cacao bean. It's a texturing agent that gives couverture chocolate a certain degree of flexibility. 
The solid form of cocoa butter is what makes chocolate look solid but feel melting.

Do you produce your own cocoa butter? 

Valrhona makes pure cocoa butter couverture chocolates according to Cocoa and Chocolate Directive 2000/36/EC, which means it does not add vegetable fat.
