Start the oven preheating to 350 F and put a pot of water on the boil for the pasta. Grate the cheese.

In another pot, warm the milk and wine on medium heat. Put in the sodium citrate, mustard and garlic powders, many grinds of pepper and a pinch of cayenne. Put in the butter, cold. Gradually whisk in handfuls of cheese until everything is melted in, then turn off the heat.

Salt the pasta water and par-boil the shells for five minutes.

Oil or spray a baking dish that holds at least 2.5 quarts. Pour in the drained pasta and then the cheese sauce. Stir to combine. Cover the dish and bake for 45 minutes.

Uncover and bake for an additional 30 minutes until brown on top. If you want it more brown, turn on the broiler at the very end. Let rest 30 min before scooping it out.

If youre not up for the sodium citrate, try my dads recipe. It uses American cheese, which already has sodium citrate in it: https://youtu.be/9iP1QXFWYkA
