Preheat oven to 350 degrees Fahrenheit
Add the salt and Sriracha to a bowl and mix thoroughly.
Line a baking sheet with parchment paper, then spread the Sriracha-salt mix evenly across it.
Place the baking sheet into the oven, then turn off the heat immediately, allowing the Sriracha salt to sit in the hot oven to dry out as the oven cools.
After 2 hours check the salt for dryness. If still not dry, repeat the above (for a lesser time), or allow the Sriracha salt to dry at room temperature.
