1poundgold potatoes (or other medium starch content potatoes), peeled and sliced into 1/4 inch thick rounds
1pound parsnips, peeled and sliced into 1/4 inch thick rounds
4tablespoonsunsalted butter, softened at room temperature
1-2tablespoonsprepared horseradish(according to heat and flavor preference)
1 1/2teaspoonssea salt
1/8teaspoonfreshly ground black pepper
1/3cupheavy whipping cream, plus more as needed
Instructions
Place the sliced potatoes and parsnips in a steamer (put the parsnips in first where they'll be closer to the hot steam with the potatoes on top since the parsnips require a little longer cooking time). Place the steamer on top of a pot of boiling water and cover with the lid. Steam for about 15 minutes or until the vegetables are tender when pierced with a fork.
Drain the pot and place the veggies in it along with the butter, salt, pepper and horseradish. Mash with a potato masher then add the cream and continue mashing until smooth, adding more cream until desired consistency is reached. Add more salt and pepper to taste. Transfer to a warmed serving bowl and serve immediately.
