Cooking time boil potatoes skin on?

The cooking time for boiling potatoes with the skin on depends on the size of the potatoes and whether you want them tender or firm. Here's a general guide:

Small Potatoes (1-2 inches in diameter):

* Tender: 15-20 minutes

* Firm: 10-15 minutes

Medium Potatoes (2-3 inches in diameter):

* Tender: 20-25 minutes

* Firm: 15-20 minutes

Large Potatoes (3+ inches in diameter):

* Tender: 25-30 minutes

* Firm: 20-25 minutes

Tips:

* Use a fork to test for doneness. The fork should easily pierce the potato.

* Overcooked potatoes will become mushy.

* Add salt to the boiling water for flavor and to help the potatoes cook evenly.

* For a crispier skin, cool the potatoes quickly in an ice bath after boiling.

Important Note: These are just general guidelines. Cooking times may vary depending on your stove, the type of potatoes, and the desired texture. It's always best to check for doneness with a fork.
