I made chocolate using cacao butter, cacao powder, sugar (icing and granulated), and dried milk powder.
In addition to being too sweet (panicked and added too much icing and granulated sugar), and too grainy (I removed the cacao butter from heat and added the other ingredients), it taseted really oily.
Why was the chocolate oily?
I made the following errors: 1. Not properly measuring everything (I couldn't find a suitable recipe) 2. Removing the cacao butter from heat and then adding the other ingredients 3. Not whisking the chocolate mixture 4. Not pre mixing the dry ingredients 5. Not sticking to icing sugar
