Add the sugar and water to a saucepan. Bring to a boil, remove from heat and add the jalapeño and 6 of the Thai chilis. Allow to steep for about 20 minutes then strain.
Add ice, tequila, orange liquor, lime juice, and 1/3 cup of the simple syrup to a shaker and shake!
Strain and serve in salted glasses over ice. You can add more of the simple syrup for an extra kick/sweetness if desired.
