Make a slit into the green chillies.
Heat a pan and roast the green chillies until they change their colour into little black.
Transfer them into a plate to cool.
In a blender add the roasted green chillies, salt and grind into a coarse paste.
Mix this paste with finely chopped onions and grated ginger.
Then transfer it into a bowl and enjoy tangy and spicy Hmarcha Rawt.
