We brought down a cooler of frozen salmon and a few frozen products we needed (we don't eat meat or chicken and didn't know what supplies would be like on island) and we had no trouble. They only confiscated the organic peanut butter at security (they deemed it a liquid). While we were there we developed a bit of a habit with Crandall's delicious conch or saltfish pates and coconut tarts and so brought a bunch on the ferry to St. Thomas to eat while awaiting our flight. US Customs at the ferry dock searched INSIDE each pate to ensure that it was not beef. Seriously.
