      Loved this recipe! We enjoyed the sweetness of the carmelized onions with the strong flavor of the horseradish! Served this with "Recipe #305341" for a totally German dinner! Also served a cucumber salad with this dinner. ZWT4.

      Wonderful! Perfect amount of horseradish. I thought it would be overpowering but the taste came through without to much heat. I used 1/2 cup low fat milk and 3 pounds of potatoes that I used my ricer for fluffy tatars! Thanks!!!

      This was a nice dish that presents beautifully. Some of us liked the carmelized onions and some of us found them too sweet. Averaged out the families' ratings and came to a solid 4.
