Instant Pot Little Smokie Mac and Cheese

Place the broth into the Instant Pot; use the saute setting to get the broth boiling, then stir in the pasta. Lock the Instant Pot lid into place. Using the manual button, choose High Pressure for 5 minutes, bringing the Instant Pot to full pressure.
When the timer sounds, use a quick release to remove all pressure from the Instant Pot. Carefully remove the lid and give the pasta a quick stir; you will notice that the pasta has absorbed all the broth (or nearly all of it), so therer's no need to drain it.
Add the beaten egg to the sour cream, then stir this mixture into the hot pasta. Add the cheddar cheese soup, shredded cheddar cheese, spicy brown mustard and the evaporated milk, mixing to combine all the ingredients together. To serve, place the mac and cheese into serving bowls; drizzle with your favorite bbq sauce, if desired, and enjoy.
