Some time back, I posted about the methods for making nice scrambled eggs. It seems like such a simple thing, but the post elicited some discussion, and some misunderstandings about the physics of cooking great eggs.
Today, I propose another basic. How to make perfect macaroni and cheese. Not the crappy watery or gummy stuff that your relatives or friends might have made, but something that will keep you coming back for more.
Set your oven to pre-heat at 450 deg F. Then boil enough macaroni noodles to make a properly sized batch. Put salt in that water and bring it to a heavy boil before you add the noodles. While the noodles are boiling, crush some garlic, and finely-chop some jalapeno peppers and yellow onions. When the noodles are much firmer than "al dente", strain them through a colander and shake them to remove excess water. Do not rinse! Return the noodles to the pot and mix in the chopped vegetables thoroughly.
Get out a nice heavy casserole dish and fill it about half-way with the noodles and vegetables. Dust the noodles lightly with a few tablespoons of flour, then cover that layer with a nice thick layer of sharp Vermont Cheddar. Make another layer of noodles with vegetables, and dust that layer with a few tablespoons of flour. Then, pour in enough milk so that the milk is not up to the surface of the top layer, but is visible between the noodles. Top with another generous layer of sharp Vermont Cheddar, and put the casserole dish in the oven. By the time the top layer of cheese is golden brown, the dish is done. Served fresh and hot, the dish is tantalizing, if a bit loose. Once the dish has been refrigerated, the combination of the flour, cheese, starch from the noodles, etc, allows the mix to solidify, so it can be easily be cut with a butter knife into single-serving sizes to be microwaved.
I left out salt, pepper, etc. That's up to you.
