Make these a little ahead, at least an hour, but they keep in the fridge for weeks.
Bring sugar and water to a simmer to dissolve sugar (be careful if making small amounts to not boil away the water). Add vinegar after removing the water from the heat, fish sauce, and salt. Pour, while still hot over carrots.
Once cool, cover and place in refrigerator. Keeps well for several week and gets better as it ages.
