Add the kosher salt to a pot of water and bring it to a boil.
Add the fusilli and cook until al dente, approximately 6 to 8 minutes.
Add the sour cream, mayonnaise, lime juice, chili powder, smoked paprika, onion powder, salt, and pepper to a small bowl. Whisk to combine the ingredients.
Drain the fusilli and rinse it under cold water until it’s completely cooled.
Add the pasta, corn, scallions, jalapeño, red pepper, cilantro, and ½ cup of cotija to a large bowl.
Start with ⅔ of the dressing and toss to combine, adding more as desired.
