Prep Water and Seasoning: Heat a pot of salted water on high to bring to a boil.Add cumin, paprika, chili powder, and salt to a small bowl and mix well, and set aside. Sear Corn: Add 1 tablespoon of butter to the pan and heat over high to melt. Add the corn and jalapeno to the pan with the butter to let it char. Cook for 1 minute, stirring often as it chars. It's ok if the bottom of the pan burns a little, you'll want that char later! Cook for another minute on high and then turn the heat down to medium-high and let it cook for another 2-3 minutes. (If using frozen, this may take a couple extra minutes)
Saute Veggies: Lower the heat to medium, add the red onion and bell pepper with 1/2 of the spice mixture, and mix well. Saute for 4-5 minutes, or until the onion begins to soften.
Create Cheese Sauce: Meanwhile, add 2 tablespoons of butter and 2 tablespoons of flour to a saucepan and heat over medium. Melt and whisk to create a roux. Slowly add milk to incorporate it all with the roux. Add the other half of the spice mixture to the milk, sour cream, and cream cheese and whisk until all of the cream and cheese is well combined, approximately 2-3 minutes. Reduce the heat to low before adding to the corn and veggies.
Cook Pasta: Add pasta to the now boiling water and cook for 6 minutes (or 1 minute less than noted on the package or only 2 minutes for fresh pasta). Drain pasta and add to the pan with corn and veggies.
Sauce: Add cheese sauce to the pan and mix with veggies, and add lime juice and mix well so it's all well coated. Add cotija and cilantro and mix well.
Serve and Enjoy! Add more chopped cilantro and crumbed cotija then serve and enjoy!
