The boiling time for potatoes and carrots can vary depending on the size and type of vegetable, as well as your desired level of tenderness. As a general guideline, you can follow these instructions:

  1. Start by washing and peeling your potatoes and carrots, if desired.

  2. Cut your vegetables into uniform pieces, such as small cubes or thin slices, to ensure they cook evenly.

  3. Place the potatoes and carrots in a large pot of cold water, making sure they are fully submerged.

  4. Bring the water to a boil over high heat, then reduce the heat to medium-low and simmer the vegetables for about 15-20 minutes, or until they are tender when pierced with a fork.

  5. Once the vegetables are cooked to your desired level of tenderness, drain them well and serve immediately, seasoned with salt, pepper, butter, or your favorite herbs and spices.

Remember to adjust the cooking time based on the size and type of your vegetables, and keep an eye on them to avoid overcooking or undercooking.
