Instructions
Heat a gas or charcoal grill to medium-high heat. Cut 6 pieces of foil into 12×12-inch squares. On each piece of foil, layer 2 cut-up potatoes, 1/6 of the onion, 1 quartered garlic clove, and 1 tablespoon of butter in that order. Squeeze the juice of 1/3 lemon over each. Season each with a dash of smoked paprika and a large pinch of salt and pepper. Fold the foil into tight packets and place over indirect heat. Close the barbecue lid and grill for 35-45 minutes or until the potatoes are tender.
While the potatoes are cooking, make the sauce by whisking together the mayonnaise, olive oil, vinegar, 1 tablespoon smoked paprika, and a large pinch of salt and pepper.
To serve, open the foil packets, spoon some sauce on top of the potatoes, and garnish with some parsley.
