Sugar and water were set on fire. I left them until they bound in a syrup. I didn't want it very consistently because I wanted chocolate in bowls. Over the syrup I added the dry part (powdered milk and cocoa), I mixed well, I put it on the fire for a few more minutes. At the end I added the semi-melted butter, I incorporated it and I added the raisins soaked in alcohol.
I put the composition in bowls (which I watered before) and I put it in the fridge.
