i used to believe that Latkes were actually buttermilk pancakes.
I was a rather finicky child and refused to eat latkes [potatoe pancakes]
My parents tricked me into eating them by telling my that indeed the Latkes were buttermilk pancakes, and that the buttermilk gave the cakes the odd texture and flavor. It wasn't until I was in my 20s that I discovered that Buttermilk pancakes and Latkes are TWO completely different food items.
