With Labor Day a week away, I wanted to give you a side dish that you can make ahead, up to a point, then toss on the grill at the last minute. Both the potatoes and sauce are so easy and fool-proof that even if you consider yourself a novice in the kitchen, you’ll impress the pants off of anyone who gets the pleasure of tasting these Lilliputian potatoes. They’re bathed in nutty browned butter, wrapped in cozy aluminum packages, and accompanied by a sour cream sauce that packs a double jolt from potent horseradish and Dijon mustard.
Oh, and, please. Don’t have a panic attack about the butter because the horseradish sauce doesn’t contain a speck of fat, not that you could ever tell from the rich, creamy flavor.
