Got a bulk hot dog eating tip from competitive eating legend “Hungry” Charles Hardy. Before the taping, I saw him open up a packet into his drink.
“What’s that??”

He made one 32 oz. cup of crystal light (looked like iced tea) and one 32 oz. of water for dipping the buns.

His explanation made total sense. After eating a few dogs, you get that fatty, greasy film in your mouth. The Crystal Light cuts the grease and gets your mouth fresh – ready for more dogs.
