This was from sunday, but I have almost gotten my Grandmother's Mac and Cheese recipie down pat. And before you scoff at it, yes Cheez Whiz makes it awesome.
1.5 lbs pasta (I prefer cavatelli)
5 tbsp butter
5 tbsp flour
1 quart whole milk
1 jar cheez whiz
1/2 cup of pecorino romano
pinch of nutmeg
breadcrumbs to coat.
make the roux, add about 2 cups of milk then the cheez whiz. use the remaining milk to get it to the right consistency (may need 5 cups).
add the nutmeg, and get to a low simmer.
Make the pasta, drain. cook slightly underdone. pour the pasta into the sauce (use a big enough pot for the sauce to allow this). mix to coat.
Add to baking pan, cover generously with breadcrumbs then put in oven for 30 minutes, or until breadcrumbs are brown and top layer of pasta is slightly hard.
