Is there a big difference between Yellow and Yukon Gold potatoes? After moving to Canada six months ago, I still haven't found Yukon Gold potatoes at the grocery stores. Instead I find Yellow potatoes and was curious as to whether or not they are considered to be the same or if they are completely different. I find that the texture is a little bit "harder" than the Yukon Gold potatoes but overall seem pretty similar. So, are Yellow potatoes the same as Yukon Gold and can they be used interchangeably?
They are often used interchangeably.  The truth is, yukon gold potatoes are a type of yellow potato.  They were developed in Canada.  You will definitely see them on store shelves here in Canada, but it can be seasonal, depending on your location.  I am in Winnipeg, and I find YG about six months of the year.
