Can anyone tell me anything about key lime juice? I looked in one store for it and couldn't find it. I looked in the baking products and in the fruit section.
Is it bottled? Refrigerated? Is it in the same area Real Lemon would be? Is it a lot different than regular lime juice?
Any help would be appreciated!

I am not sure if its key lime or not but lime juice is next to the bottled lemon juice. Most likely in the juice section in the store.

Otherwise, I would get fresh key limes and squeeze them yourself.

Key Lime juice is hard to find. A large gormet store usually knows what you are talking about. made the mistake of buying Rose's Lime Juice{used for drinks}.
Good Luck.
