So June Kept talking about a bloody marry using Clamato juice, This wouldn't be a bloody Mary but a Ceaser. the main difference being Clamato juice has a "dried clam broth" as described by the website. While the main difference being clam juice, both are prepared and served the same way. It might be a Canadian thing but here most people don't use a "Ceaser mix" (as is insinuated when googling Ceaser the drink) most people just use Clamato juice.
