In a bowl, mix the salt with the Sriracha. Spread the mixture out thinly on the baking sheet and allow it to dry slowly, uncovered, for a day or two, stirring once or twice. It can then be stored for future use in an airtight container at room temperature.
Preheat the oven to 350°F. Spread the Sriracha salt out thinly on a baking sheet lined with parchment paper. Put the baking sheet in the oven and turn off the heat immediately. Allow the salt to sit in the residual heat until completely dry. The drying time can vary greatly depending on many factors, but it usually ranges from 2 to 3 hours. Okay, so it may not be done “in a pinch” per se, but it does cut the drying time down from days to hours.
