What About Using Fresh Potatoes?
I must confess that sometimes I use instant mashed potatoes and have fed them to my guests. Most people won’t even know the difference if you add a few extra ingredients to the potatoes. When making instant mashed potatoes, I always use a little extra butter, and I will swap the milk for some half-and-half if I have it available – these two ingredients will make the potatoes nice and rich. Let me just say that you can, of course, make this dish with fresh potatoes. I would use about two pounds of potatoes when making this dish from scratch.
A Brief History of the Potato
The Incas in Peru were the first civilization to cultivate potatoes around 8,000 – 5,000 B.C. After the Spanish Conquistadors conquered Peru in 1536, they discovered potatoes and brought them to Europe. Potatoes landed in the US in 1621 when Nathaniel Butler, the Governor of Bermuda, sent vegetables, including potatoes, to the Jamestown colony in Virginia. Farmers everywhere eventually discovered that potatoes were easy to grow and in time it became known that potatoes contained nearly all of the vitamins necessary for human sustenance. You can read much more about the long history of the potato.
Some Interesting Facts About Potatoes
In the 18th Century Antoine-Augustin Parmentier, a French pharmacist convinced the French to eat potatoes and saved thousands from starvation during the European famines in the 1700’s. In 1767, Parmentier created a feast for King Louis XIV that consisted solely of potato dishes, a concept he realized was possible after being imprisoned in Germany and fed only on a diet of potatoes. Benjamin Franklin, the American Ambassador to France, attended Parmentier’s feast
- During the Klondike gold rush in Alaska, (1897-1898), gold miners paid for potatoes in gold. Gold was plentiful but nutritious vegetables weren’t.
- In 1995, the potato starred as the first vegetable to be grown in space. NASA and the University of Wisconsin created a technology that would enable astronauts to be fed on long space voyages. It is hoped that in future potatoes will help feed human colonies on distant planets.

This was a potato casserole my mother-in-law enjoyed, which was surprising. She is very picky, and has told me that plain baked potatoes with nothing on them are “too salty”. Sometimes I stare at her and think my husband must have been adopted.
