Remove the stems of red chilly and soak it for half an hour in water.
Now boil soaked red chilly in the same water for 5-10 minutes.
Once boiled discard the water and grind it into smooth paste by using little water.
Heat oil in a pan, once the oil becomes little hot add garlic, ginger and sauté it for few seconds until raw smell goes off.
Add chilli paste, sugar, vinegar, salt, soya sauce, black pepper mix it well and cook on medium flame until the paste gets slightly thick and leaves oil.
When the chutney cools down store it in an airtight jar.
