There are usually vendors at the Marigot market for spices. For sauces, Super U and Carrefour both have many unusual pre-made sauces in bottles, certainly unlike anything in my grocery stores around here. We often just gawk in the grocery store at all the unusual items.
There is an interesting sauce that I found there. I can't remember the name other than "ketsup". I believe it's like a Catsup, Soy Sauce mixture that was great when grilling meats. Cheers and good luck with that horrible description! i
Wendell--if we buy sauces like that, we just put it in a checked bag. Usually we don't open it on island, preferring to wait to be 'surprised' when we get home. Although truthfully, I don't think there would be any problem with it regardless. What would be the exact issue? A sauce would not be a fruit or vegetable or meat? Now, as far as spices, I guess the dog might alert on them, and they might think they were drugs?
IF it is a "non sealed" food product you could have problems. Some spices sold a the Marigold market are in bulk, put in a plastic or paper bag. These you could have issues with.
Several times we had brought back spices that had been in small baggies from the Marigot Market---especially "magic spice" with no problem. Then once what we had was confiscated. Since then we haven't attempted to bring anything home.
Near the fish counter - we would buy from Olive and Keven - Olive handpaints the bottles and the sauces are great On my last bottle know and in withdrawl is closing in
On our last trip - March /April this yr could not find Olive but did find her daughter Sandy who had a booth at the market near the coconut stand which on the roadside [which is across from the art gallery store - also a good stop while in Marigot]
We always take some bubble wrap when we travel so we can wrap bottles for checked luggage take home
