When you bake a potato, the starch granules absorb the moisture within the potato. Within the confines of the potato skin, moisture soon turns to steam that expands with great force, separating the starch granules and making a fluffy baked potato.
How do you keep potatoes from getting mushy?
You're cooking mashed potatoes on high heat. Cook mashed potatoes low and slow to give them the perfect consistency. If you boil them fully, they will be watery and loose, says McAllister. And if you turn them off too soon, they will be raw. Also avoid a masher and go for a ricer, instead.
Are potatoes still good if they're soft?
Raw potatoes should be firm to the touch with tight skin that's free of large bruises, black spots, or other blemishes. If a potato has become soft or mushy, you should throw it out. Though it's normal for potatoes to smell earthy or nutty, a musty or moldy odor is a hallmark of spoilage.
Should potatoes be soft after boiling?
Know your times. Boil 10 to 12 minutes for cubed, 15 to 20 for whole medium-sized, or 25 to 30 for whole russets. Check with a fork or knife. Potatoes are done when they are tender enough that a utensil easily slides into the middle.
