How long does it take whole potatoes to cook thoroughly?

The time it takes to cook a whole potato thoroughly depends on several factors, including:

* Size: Larger potatoes will take longer to cook than smaller ones.

* Variety: Some potato varieties are denser than others, meaning they need more time to cook through.

* Method: Boiling, baking, roasting, and frying all have different cooking times.

Here's a general guide:

* Boiling: 15-20 minutes for medium-sized potatoes.

* Baking: 45-60 minutes for medium-sized potatoes.

* Roasting: 45-60 minutes for medium-sized potatoes.

* Frying: 5-10 minutes for diced potatoes.

To test for doneness:

* Boiling: Pierce the potato with a fork. It should be tender and easily pierced.

* Baking/Roasting: The skin should be crispy and the flesh should be tender when pierced with a fork.

* Frying: The potatoes should be golden brown and crispy.

Tips:

* Cut large potatoes into smaller pieces: This helps them cook more evenly.

* Don't overcrowd the pot/pan: This will prevent potatoes from cooking evenly.

* Use a meat thermometer: Insert the thermometer into the thickest part of the potato. It should read 210 degrees Fahrenheit for a fully cooked potato.

Remember: These are just estimates. It's always best to check the potatoes for doneness before serving.
