Step 1

In a small heatproof bowl, add in the sugar, chili flakes, and garlic. Pour in the boiling water. Mix well until the sugar has dissolved. Add in the lime juice and the salt. You can start with the least amount of salt and just add more depending on your desired saltiness level.

Step 2

Leave the sauce to cool before storing in an airtight container. Keep the sauce in the refrigerator until ready to use. The flavours will get stronger as it sits. This sauce is good for up to 2 to 3 weeks.
