These will be the most popular item on your brunch table, guaranteed. Serve them with a side of malt vinegar to really take it to the next level. Oh, and in this recipe the garlic is boiled with the potatoes, which softens its pungency. No one likes too many aggressive flavors in the morning! Duck fat can be found in the frozen section of most butcher shops. It adds fantastic flavor to the potatoes, but olive oil can easily be substituted. Freezing Tip: Both of these potato side dishes should be served immediately, but they also reheat nicely in a blazing hot oven. Should you wish to freeze the hash browns for convenience sake, place them in a single layer on a parchment paper-lined cookie sheet and freeze them until solid. Transfer the hash browns to a sturdy resealable plastic bag and remove as much air as possible. Hash brown will keep, frozen, for 8 weeks.
