ABC is an acronym for Ais Batu Campur or literally translated as mixed shaved ice. This product is categorically under soft ice-cream which includes the sherbets, cendol and ever-popular ice-blended.
Normally taken during hot summer :) or whenever you have hot food & spicy like satay or chilli-based dishes
It has varieties of condiments like roasted peanuts, jelly etc sometimes served with ice-cream. I love it when it has lychee...simply cool and amazing.
