This batch set up so quickly, I barely had time to do anything. My slamming and dropping the soap in the mold on the floor didn't clear up all the air holes as you can see in the middle photo. I did the tongue zap test, and there's nothing, so I think it is just aesthetic.
They still smell great! The dry sprinkles of espresso looks like melted chocolate drips now. They fused to the soap during the gel.
Now I need a latte. Excuse me while I go squeeze some espresso out of my Gaggia God.
