On vacation in Vietnam, I was walking through a street market in District 4 of Ho Chi Minh City yesterday when I spotted these things. They have a soft black shell that you can peel open with your fingers (leaving inky black residue on your hands), with a soft nut inside that's like a young Brazil nut.

Does anyone know what these are??
