      These were good potatoes served with our roast beef and onion gravy. However, I was disappointed that the horseradish flavor wasn't more pronounced. The caramelized onions added a lot to the blend, though. My hubby really liked that touch.

      It takes a lot to make us go WOW over mashed potatoes, but this was a wow recipe! It was great, easy to make and tasted fantastic. Allow more than 10 minutes to caramelise your onions for a real treat! And the vinegar is a good addition along with the other tangy ingredients. We ate this with lamb in quite a sweet sauce, so it went really well.

      We are such a meat and potato family that when this was served...our reaction was..."What a different recipe!" Loved the mix of the onion, brown sugar, mustard with the kick of horseradish! It was hard to know which way my taste buds were going. These were really good and will be making them again. Thanks for posting!
