Whisk together the Secret Sauce ingredients in a small bowl.
Melt the butter in a skillet set over medium heat.
As soon as the butter melts and starts to bubble, gently stir in the garlic and cook for about one minute. You just want to take off the raw edge of the garlic, you do not want it to brown.
As soon as the garlic is ready, stir in the secret sauce to stop the garlic from cooking further.
Turn off the heat set aside until the noodles are ready.
Cook the pasta in generously salted water for the full suggested cooking time. You want the pasta to be fully cooked, and perfectly tender, not al dente.
Use tongs to transfer the cooked pasta to the skillet with the secret sauce, allowing some of the pasta water to come along during the process.
Toss the noodles in the sauce until they are completely coated.
Add in the cheese and stir to fully incorporate.
Drizzle in additional pasta water if the noodles are too dry.
One the pasta is completely sauced, transfer to plates and top with some chili flakes and sliced scallions.
