Mac and Cheese

I found this recipe on one of my favorite blogs..."Hold the Onions." I was excited to find a Mac and Cheese recipe that didn't involve flour. This recipe was easy and everyone liked it, except for 2 little boys who couldn't believe we thought this was better than Kraft. Go figure.

3 1/2 cups water
1 can evaporated milk
12 oz. elbow macaroni (3 cups)
salt and pepper
1 tsp. cornstarch
1/4 tsp. dry mustard
2 drops Tabasco
2 cups shredded cheddar
2 cups shredded monterey jack
3 T. butter

*Bring water, 1 cup of the milk, macaroni and 1/2 tsp. of salt to a boil, stirring often, until pasta is tender.
*Whisk remaining milk, cornstarch, mustard and Tabasco together and stir into macaroni. Simmer for 1 minute until thickened.
*Take off heat and add cheeses and butter. Salt and Pepper to taste. Serve immediately before sauce starts to thicken.
