Imagine a room full of toddlers holding water balloons. That’s your potato starch during cooking. Now imagine you, the parent, running through that room with a baseball bat. That’s your masher. When those starch granules explode, they release long, sticky chains called amylose and amylopectin. These chains then tangle together into a gummy net.
It’s the same chemical reaction that makes glue. In fact, potato starch is historically a base for wallpaper paste. So when you make gummy mashed potatoes, you haven’t failed at cooking. You’ve accidentally succeeded at home improvement. Enjoy licking the spoon; it tastes like floor adhesive with a hint of dairy.
Here’s the brutal truth: time and violence are your enemies. The longer you mash, and the harder you mash, the more those starch chains link up. A food processor is a guaranteed trip to Glue Town. It spins so fast it turns your spuds into a sticky paste that could patch drywall.
