Cut stems off chilis and place into a saucepan. Wear gloves if you plan to remove the seeds. (Remove seeds for less spice)
Add vinegar to the pot. Put on the stove at medium high heat and add bay leaves, garlic cloves, and salt.
Simmer on medium-high heat for 20 minutes or until chillis are soft.
Once the mixture is cooled down, put into a blender and blend until smooth.
Pour the sauce through a sieve to remove any excess seeds. Repeat until no seeds are in the sauce.
Put into an airtight container and ready to use!
