Where to buy jars of clam juice in Baton Rouge? Would rouses have this?

Yes. In my Rouses it's by the tomato juice, on the top shelve.

Not sure about Baton Rouge, but I know Illusions in Woodville has plenty

In a bind, ask. I have had to before. Usually it is with the canned seafood/Tuna/Canned Shrimp, etc. Usually on the top shelf. Sometimes, they have no idea where to put it, but almost all groceries have it. Small bottle, sort of like an old milk bottle.

You found any, what you made with it
