Potatoes are shockingly cheap too, for some reason I suddenly 'noticed' that at the weekend, around 40p/kg, (uh.. 25c/lb ish) that's crackers (cookies for cheese) isn't it?
I'm sure there's other things you have or have variety in that we don't, but I wouldn't fancy not having a choice of potatoes. Though I almost always get Maris Piper to be honest, so it's not even really about choice as such, just knowing what I like and what I'm getting, I only buy 'white' if there's nothing specific (and more appropriate) available.
Sometimes 'white' will tell you what the actually are (this batch) on the date/producer label bit, or what they might be a mix of, which is nice.
Well, that's more than I've previously written or thought about potatoes...
Is it possible you are in an environment where potatoes aren’t very profitable crops? Because I see lots of variety in potatoes routinely and “North America” is a very big place to be saying anything about the food ways.
