2.5 pounds red skin potatoes, skinned
1/2 large onion (preferably yellow)
2 tsp brown sugar
1 Tbs balsamic vinegar
2 Tbs dijon mustard
1 Tbs lemon juice
1 Tbs mayo
Pepper
2 Tbs heavy cream
2 Tbs cooking water (saved from the potatoes)
4 Tbs butter, divided
Here's how you do it:
Melt 1 tablespoon of the butter in a medium saucepan or skillet over medium-high heat. Add the onion and sugar and sauté for 10 minutes or until the onions are caramelized. Remove them from the heat and stir in vinegar, which will help release all the brown deliciousness from the pan.
In a separate bowl, mix together the mustard, lemon juice, mayo, and 2 tablespoons of cooking water. Add this mixture and caramelized onions to your mashies and stir well.
You are going to want to eat the whole pot of potatoes, but I suggest balancing it out with some veggies ;)
Enjoy!
