Hi. My favorite food is mashed potatoes.
Yum! I love those too! Recipes started floating around as far back as 1747! 
I guess they are a real classic. What country was that in?
The recipes started in a book by hannah glasse called The Art of Cookery!
Wow. I have never read a cookbook that old. I have seen ones from the 19th century though. 
There are so many variations in recipe. There is one from France that adds egg yolk in it. 
I like they way they look when they are piped into fancy shapes. I bet the egg yolk would help them hold their shape.
It sure does. They are known as Duchess Potatoes. They use a pastry tube to pipe it out into ribbons.  
They're so pretty. And the top of Shepherd's Pie looks nice that way, too. Do you like shepherd's pie?
I sure do! So yummy. And it can have many flavors depending on the seasoning for the potatoes! Some popular ingredients are garlic, bacon, cheese and sour cream.
