There are ways of making this aubergine side dish but in my family, there was always a special wooden chopping tool that was used to chop these eggplants once cooked on BBQ. If you prefer it chunky, you may use a wooden fork, or a wooden cleaver to smash the eggplant - ideally to avoid metal blades so if you happen to have a coated blade or a plastic one to blitz this would be great. The more you blitz them the smoother the paste will be and more white in color.
