Do you start potatoes in cold water or boiling water?
Cold water. Potatoes are dense, so starting cold helps the heat move to the center before the outside overcooks. The only time I start with boiling water is when the potatoes are already cut very small and I’m in a real hurry, but cold water is more reliable.
How much salt should I add to the water?
For a medium pot (about 3 quarts of water), add 1 tablespoon kosher salt (Diamond Crystal). If you’re using Morton kosher salt, use a bit less, about 2 to 2 1/2 teaspoons. The water should taste pleasantly salty, like a mellow soup, not like the ocean.
How do I know when potatoes are done?
Pierce with a fork or paring knife. It should slide in with very little resistance. Ideally, the fork slides in easily and you can lift the potato without it collapsing, but it should still hold its shape. If the potato cracks aggressively or falls apart, you went a little long. Still tasty, just handle gently.
Why did my potatoes fall apart?
Usually one of these: the pieces were cut unevenly, the boil was too aggressive, or they cooked too long. Keep it at a steady simmer, cut evenly, and start checking early.
Should I peel potatoes before boiling?
Depends on the vibe. For potato salad, I often boil whole with skin on, then peel while warm. For mashed potatoes, I usually peel first. For weeknight buttered potatoes, skin-on is my favorite because it’s less work and more flavor.
How long to boil potatoes?
It depends on size, type, and your simmer (gentle simmer assumed here, with typical “baby” and “medium” sizes). As a general guide: baby potatoes 12 to 18 minutes, cubed potatoes 10 to 15 minutes, whole medium Yukon Gold or red potatoes 20 to 30 minutes, and whole russets 30 to 45 minutes. Start checking early.
Which potatoes are best for boiling?
If you want potatoes that hold their shape (salads, buttered potatoes), go with waxy types like red potatoes. If you want softer, fluffier potatoes that break down more easily, starchy russets are your friend. Yukon Gold sits happily in the middle and works for almost everything.
Does altitude change boiling time?
Yep. At high altitude, water boils at a lower temperature, so potatoes can take a little longer. Keep the same method, just plan on adding a few extra minutes and rely on the fork test.
