Never have I ever tried this type of pancakes. I have eaten a lot of caviar though and I like it. Maybe I will give them a try but I will replace the sour cream with something else. I am not sure what with at the minute but you got me thinking and I thank you for this as I love to experiment in the kitchen. Over here in England we even have a National Pancake Day, this year it will be on 1st March and traditionally people have pancakes with sugar and lemon. I personally don’t as I do enjoy a savoury pancake better.
