• Wash and dry produce. • Peel and dice potatoes into 1/2-inch pieces. Place in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 10-12 minutes. Reserve 1/2 cup potato cooking liquid, then drain.

• Meanwhile, peel and mince or grate garlic. Halve, peel, and thinly slice onion. • Heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add panko and cook, stirring, until golden brown, 3-5 minutes. Turn off heat; transfer to a small bowl and season with salt and pepper. Wipe out pan.

• In a second small bowl, combine mayonnaise with a pinch of garlic (taste and add more if desired). Season with salt and pepper. • Heat a drizzle of oil in pan used for panko over medium heat. Add onion; cook, stirring occasionally, until browned and softened, 5-7 minutes. (TIP: If onion begins to brown too quickly, add a splash of water.) Stir in vinegar and 1 tsp sugar (2 tsp for 4 servings); cook until onion is caramelized and jammy, 1-2 minutes more. Season with salt and pepper. Turn off heat; transfer to a plate. Wash out pan. TIP: Cover plate with foil to keep warm.

• Return potatoes to pot; mash with sour cream and 2 TBSP butter (4 TBSP for 4 servings) until smooth and creamy, adding splashes of reserved potato cooking liquid as needed. Stir in half the Monterey Jack; taste and season with salt and pepper.

• Form beef* into two patties (four patties for 4 servings), each slightly wider than a burger bun. Season all over with salt and pepper. • Heat a drizzle of oil in pan used for onion over medium-high heat. Add patties; cook to desired doneness, 3-5 minutes per side. In the last 1-2 minutes of cooking, top each patty with remaining Monterey Jack; cover pan to melt cheese.

• While burgers cook, measure out two TBSP-size portions, two 1/4-cup portions, and two 1⁄3-cup portions of mashed potato mixture. Form into balls using your hands, then roll in toasted panko to coat. TIP: The potato mixture will still be warm, so wear food-safe gloves for less mess! • (We sent a carrot for decorating—peel and cut it into different shapes to use as eyes, arms, and buttons, and transform your snowballs into snow people!)

• Halve and toast buns until golden. • Spread cut sides of buns with ketchup and as much garlic mayo as you like. Fill with patties and as much caramelized onion as you like. • Divide burgers and potato snowballs between plates; stack snowballs to create snow people. Serve. Ground Beef is fully cooked when internal temperature reaches 160°.
