Alfredo is a diva. It’s made from butter, cream, and Parmesan, and it loves to thicken up as it cools. Think of it as the sauce equivalent of a cozy blanket—it just gets more solid the longer it sits.
Sometimes, you might have added too much cheese. Or maybe you let it boil (please, never boil it! That’s a one-way ticket to Gravy Town). Don’t blame yourself. Blame the sauce. It’s temperamental.
The good news? Thinning it back down is stupidly easy. You just need the right tools and a little patience. No culinary degree required.
