Tip – I suggest you wear gloves when handling chillies, as they can cause burns on your hands.
Cook The Chillies
In A Traditional Pressure Cooker
Add the chilies, ginger, garlic, and water to a pressure cooker and stir well.
Close the lid of the cooker and pressure cook for 3 whistles on high heat.
Remove the cooker from the heat and let the pressure release naturally. Open the lid.
In An Instant Pot
Add the chilies, ginger, garlic, and water to an Instant Pot and stir well.
Close the lid and set the valve to the sealing position.
Press PRESSURE COOK and set the timer to 3 minutes at high pressure.
Once the timer goes off, let the pressure release naturally.
Open the lid.
Blend The Sauce
Cool the chilies to room temperature and add them to a blender along with the liquid.
Add vinegar, salt, and sugar, and blend to make a smooth paste.
Pass the mixture through a fine-mesh strainer and discard the leftover.
Cook The Sauce
Transfer the mixture to a frying pan and cook for 4-5 minutes over medium heat until the sauce is thickened.
Remove the pan from the heat and let the sauce cool down to room temperature.
Transfer it to an airtight glass container and refrigerate for up to 15 days. Use as desired.

Notes
Wear gloves while handling the chilies to avoid burning your palms.Remove the seeds from the chilies if you like your sauce less spicy.Stay away from the steam coming out of the pressure cooker, as it may also cause burning.You can also cook the ingredients in a pan if a pressure cookeris not available.
