We didn't do too much cooking this past week, but we did make this Potato and Celery Root Mash recipe to go with some brisket (that we'd previously made and froze).
I don't know if I can eat regular mashed potatoes from now on without thinking about this recipe. It's easy to make and only involves 7 ingredients: potatoes, celery root, horseradish, sour cream, Dijon mustard, butter and salt.
We made half the amount (the recipe is for 6-8 servings) and used horseradish cream that's easily found in the grocery store instead of actual horseradish which our store was out of. It was my first time cooking celery root -- which we had to go to Central Market, our specialty grocer, to buy. It along with the horseradish added a nice dimension. We'll definitely be making this again!
