I was bringing back as a gift for my mom some manjar blanco, which is a Colombian version of dulce de leche, quite tasty. It comes packed in a coconut shell, which is then wrapped in plastic (with Spanish writing explaining what it is), and it is not liquid per se. The TSO spent a lot of time looking at it, turning it over and over, without ever once asking me what it was. Eventually, she just handed it to me and I left. Note: I was not coming from Colombia, I was flying between two domestic airports.
