Stovetop Mac N' Cheese - cooking recipe

Ingredients

1 (16 ounce) box pasta
1/4 cup butter
1/4 cup flour
1/2 teaspoon salt
1/2 teaspoon pepper (White if available)
3/4 teaspoon dry mustard
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
2 cups evaporated milk
8 ounces cheddar cheese (shredded)
1/4 cup parmesan cheese (shredded)
2 slices American cheese

Preparation

Boil a pot of water and cook pasta \"al dente\".
In a medium pot, melt butter on low heat.
Mix all the dry ingredients together and whisk into the melted butter.
When the butter and flour are incorporated and hot start adding the milk.
Don't stop whisking from the time you add the flour until the milk is all inches.
Only adding a little milk at a time as to avoid the flour lumping (maybe 1/2 cup at a time).
Heat the flour/milk mixture until its bubbling (stirring very often or it will burn).
Once it's bubbling start adding the cheese a little at a time making sure it melts before adding more.
After all the cheese is in and melted just add it to the cooked pasta and serve .
