German potatoes are called "Kartoffeln" because the word "Kartoffel" comes from the Italian word "tartufolo," which means "truffle." When potatoes were first introduced to Europe, they were initially mistaken for truffles due to their similar appearance. Over time, the word "tartufolo" evolved into "Kartoffel" in German. Therefore, German potatoes are called "Kartoffeln" due to the historical association with the Italian word for truffle. **

Early potatoes are suitable for mashed potatoes, as they have a creamy texture and thin skin that makes them easy to mash. Their flavor is also mild and buttery, which is ideal for mashed potatoes. Additionally, early potatoes tend to be smaller in size, making them quicker to cook and easier to mash compared to larger varieties. Overall, early potatoes can make delicious and creamy mashed potatoes. **

It depends on the recipe and personal preference. New potatoes have a thinner skin and a sweeter flavor, making them great for roasting, boiling, or using in salads. Regular household potatoes, such as russet or Yukon gold, have a thicker skin and a more starchy texture, making them better for mashing, baking, or frying. Ultimately, the choice between new potatoes and regular household potatoes depends on the specific dish you are preparing. **

As a general guideline, you can estimate that one medium-sized potato yields about 1/2 to 3/4 cup of mashed potatoes. So, for a side dish serving for 4 people, you would need around 2-3 medium-sized potatoes. It's always a good idea to have a few extra potatoes on hand just in case you need to adjust the consistency of the mashed potatoes. **

To cook potatoes in hot water in an energy-efficient way, start by using a small amount of water in a covered pot to minimize heat loss. Bring the water to a boil, then reduce the heat to a simmer to conserve energy. Additionally, using a lid on the pot will help retain the heat and cook the potatoes more efficiently. Finally, consider using a smaller pot that fits the amount of potatoes being cooked to minimize the amount of water and energy needed. **

To boil potatoes in hot water in an energy-efficient way, start by cutting the potatoes into smaller, uniform pieces to reduce cooking time. Use a lid on the pot to trap heat and reduce the amount of energy needed to maintain boiling. Bringing the water to a boil quickly using a kettle before adding it to the pot can also save energy. Lastly, once the water is boiling, reduce the heat to a simmer to maintain the temperature and cook the potatoes gently without using excess energy. **
