Why are my mashed potatoes runny after freezing them?

Mashed potatoes get runny after freezing because the water in them forms ice crystals that break down potato cell walls, releasing moisture upon thawing, a process intensified by starch retrogradation, while a lack of sufficient fat (butter/milk) exacerbates the watery texture, leading to mushy, soggy results when reheated. Using waxy potatoes, adding more fat, cooling completely before freezing, and reheating carefully can help prevent this.
