The length of time it takes to boil large potatoes will depend on the size of the potatoes and the method of boiling. Here is a general guideline for boiling large potatoes:

  1. Start by scrubbing the potatoes thoroughly to remove any dirt or debris.

  2. Place the potatoes in a large pot and cover them with cold water.

  3. Bring the water to a boil over high heat.

  4. Once the water is boiling, reduce the heat to medium-low and let the potatoes simmer gently.

  5. Cook the potatoes for about 20-30 minutes, or until they are tender when pierced with a fork or knife.

  6. Drain the potatoes and let them cool slightly before handling or serving.

Note that cooking times can vary depending on the size and variety of potatoes, so it's always a good idea to test them for doneness with a fork or knife.
