What happens when potatoes are over mashed?

When potatoes are over-mashed, their internal starch cells break down, releasing too much starch and causing them to become a gummy, gluey, or pasty texture instead of light and fluffy, often described as "wallpaper paste". This happens because the mechanical force of over-mixing ruptures the starch granules, making them sticky and dense, a problem usually avoided by using gentler tools like a ricer or hand masher.

Why did my mashed potatoes get gummy?

Cooking them causes the starch granules within the potato cells to grow larger but some will burst which gives mashed potatoes their cohesive consistency. If there is too much gelled starch from either overcooking or mashing too much, the potatoes will turn gummy and have a glue-like consistency.

No, 30 minutes isn't too long for boiling potatoes, especially for large, whole ones; it's often the perfect time for them to become tender, though smaller or diced potatoes cook much faster (10-20 mins), so always test with a fork to ensure they're soft but not mushy. Key factors are size, cut, and potato type, but starting in cold, salted water and simmering ensures even cooking, making 30 minutes appropriate for big spuds.
