I just bought some pepper. I didn't know what kind to get so I bought the kind that has its own grinder built in. Then I had to chose between the black peppercorns or the peppercorn medley. I got the medley and it has black peppercorns, pink peppercorns, white peppercorns and green peppercorns. What's the difference? And if you say color I'm gonna flip you off.
