Looking for Old Sour   

I am trying without success to find a place to buy Old Sour on line.

I grew up eating fish with Old Sour and I haven't had it in years. Old Sour is an old time very South Florida and Bahamian recipe made with key limes or sour oranges, hot pepper and a lot of salt. Once you make a batch it lasts forever and you only need a drop or two for a peice of fish. We always had a big crock of it in the pantry.

I have found a recipe on line but never a person crazy enough to make it and sell it.
