Shavuot Recipes: Gluten-free Macaroni and Cheese

I'll tell you this right now: There is absolutely zero that is healthy about this recipe. Although I measured a few things, I'm very much in a "play it by feel" kind of recipe experience.

Ingredients
1 package cooked Tinkiyada gluten-free elbow noodles
2 cups milk separated into 1.5 and .5 cups
4 Tbls tapioca starch
1 tsp mustard powder
salt and pepper
plenty of shredded cheese (I used cheddar and mozzarella)

Directions

1. Cook the Tinkiyada noodles according to package instructions. 
2. When the noodles are about 5 minutes from being done, start on the sauce. 
3. In a bowl, whisk together the .5 cups milk with the tapioca starch until combined and not lumpy. 
4. Heat 1.5 cups milk over a medium heat until it starts to steam slightly. 
5. Mix the starch/milk mixture into the milk on the stovetop and add in the mustard powder, salt, and pepper. 
6. Throw in as much cheese as you want and continue to stir as the cheese melts. 
7. Go crazy with the cheese, and just watch as the sauce thickens. If it gets too thick, add more milk. 
8. Mix with the noodles, and enjoy!

You can also throw in peas, tuna, salmon, and any other interesting add-ins you'd like. This freezes really well, which is what I've done for Shavuot.
