Your best recipe for macaroni and cheese?

This is the recipe I use given by a friend of mine called Myrna. So I call it Gratin de Macaroni a la Myrna or Myrna's Mac and Cheese. It is very good.

Gratine de Macaroni
· 1 box of Penne pasta (16 oz)
· 16 oz grated extra sharp cheddar cheese (4 cups)
· 1 whole onion (medium size-chopped small)
· 1 can evaporated/carnation milk
· 2 tbsp of mayonnaise
· 2 tsp mustard
· 1 Stick of butter plus a little bit more
· Dash of nutmeg
· Dash of Thyme
· Salt (to taste; add after you’ve tried the sauce with the cheese)

PREPARATION FOR PASTA:
1. Boil pasta in a large pot (let water boil first, then add pasta)…add half spoonful of salt to the boiling water
2. Once pasta is cooked (do not let overcook-keep firm), drain the water out and rinse with cold water
3. Once all the water is drained
4. Put pasta in a large bowl for mixing
5. Mix in the mayo and mustard

PREPARATION FOR THE SAUCE “Bechamel sauce”
6. In a deep pan, melt the one stick of butter.
7. Once melted add the onion and cook until translucent
8. Add milk.
9. Once boiling mildly, add the cheese
10. Stir very slowly until sauce thickens with a wooden spoon
11. Taste and add salt if necesary
12. Pour bechamel sauce on the pasta and mix well
13. In a pirex pan, add a little bit of butter around pan so that pasta does not stick to bottom when baking
14. Add pasta in pan
15. Sprinkle some parmesan cheese on top to create the “gratin-(crust on top)”
16. Add small cubes of butter on top layer of pasta as well
17. Put in the oven and bake for 30 minutes/350 degrees

Do you mean a mac and chese that you can cut into squares rather than the gooey sloppy kind? That's how I make it usually - here's is a recipe using roasted roots (which is pretty Southern-y) but you could easily use ham hock, or just ham, different veggies, or whatever flavor profile you are going for:

Gourmet has a great recipe. It calls for extra shap white cheddar, which is what my grandmother always used. It is very rich and creamy.
