In a mixing bowl, combine the salt, lemon juice and Sriracha and mix well.
Spread the mixture on a baking sheet lined with parchment paper, and pop it in the oven preheated at 200 degrees.
Let it roast for 10 minutes, and then turn off the oven, letting the salt stay in there for 8 hours, ideally overnight.
Remove clumps, store in an airtight container and use it as a seasoning for your favorite foods.
Notes
Make sure the spicy salt is completely dry and has the perfect texture before you store it in an airtight container. You can pulse the salt in the food processor or blender to remove any clumps, or layer it with another parchment paper and roll a rolling pin over it to break up the chunks of salt. Depending on your personal preference, you can choose to grind the mixture and turn it into fine salt, or leave it chunky.If the salt seems like it is getting some moisture and turning soggy, you can transfer it to a skillet, and let it dry on low heat for a few minutes. Turn off the heat at around the 3-4 minute mark and let the salt stay in the skillet until it cools down.
