If you have a juice extractor, use it to get the juice from the ripe mango. Run the pulp through a second time with 1/4 cup water. If you don't have a juice extractor, puree the mango in a food processor, then add the water. Strain.
Combine all the other ingredients in a non-metallic bowl, cover, and chill for at least four hours. Add salt, Tabasco and black pepper to taste.
