Chef's Notes
Listen closely, culinary adventurer! Slicing potatoes to an even 1/8 inch is your ticket to glory. If your slices resemble doorstops, they will remain crunchy while the cream boils away into oblivion.
Pro Tip
Never skip the cold water rinse! Removing surface starch is the secret weapon that stops your potatoes from gluing together into a gummy disaster instead of tender, delicate layers.
Kitchen Catastrophe Warning
If you fail to seal the sheet pan tightly with foil during the first bake, the steam escapes, leaving you with dry, crunchy potato chips swimming in scorched cream. Do not let this tragedy befall your kitchen!

The Culinary Science
Heavy cream has a high fat content that prevents the dairy solids from curdling when exposed to high heat and salt, creating a velvety, luxurious emulsion instead of a split mess.
