I served this at a Scandinavian party and the results were positive. I did however add more lemon juice and more sugar. I baked the potatoes the day ahead and peeled them. It went over quite well and was pretty too.
I made this recipe before my wife did from my Finnish cookbook and it really is a good beet salad. We took it to a potluck and some people were put off by the pink color but liked it when they tasted it. It has an unusual combination of ingredients but its worth making and trying for yourself.
