When you cook butter on its own for long enough you will get some grainy, brown residue at the bottom.

When butter melts you can see its has the oil (clarified butter) then the little white solid bits. When cooked these solids can burn. This is why regular butter burns on its own in a pan.

Try clarifying your butter by melting it gently then pouring off the clear oil, leaving behind the white residue.
dean0000 Reviewed by dean0000 on . orange salty like residue when making butter? I am not sure what happened, but this is only my second time making cannabutter...There was a rust color residue that settled at the bottom of the butter after I finished..The smell was very potent, and it had some granular salts in it? The color scares me though..I know the buds had a lot of orange hair in it and some orange, and also it was super sticky and strong smelling..I have the mixture in the fridge right now. I just wanted to get some input as to why it may have turned orange? Rating: 5
