The Golden Rule
"Never skip the resting period at the end! Allowing the mac and cheese to sit for 10 minutes lets the starches reabsorb excess moisture so you get distinct, creamy scoops instead of a soupy landslide."

Chef's Notes
Caramelizing onions is a test of true character. Do not rush them with high heat, or you will burn them instead of achieving that sweet, jammy perfection.
Pro Tip
Shred your own Gruyère from a block rather than buying pre-bagged; pre-bagged cheese contains anti-caking starches that ruin the silky texture of your béchamel sauce.
Kitchen Catastrophe Warning
Beware of rushing the onion caramelization by turning the burner up to high, resulting in bitter, burnt char-coal rings that taste like despair and ruin your entire afternoon.

The Culinary Science
Deglazing the Dutch oven with dry sherry uses alcohol to dissolve flavorful browned bits stuck to the pan, releasing compounds that water alone cannot touch.
