Cooks' notes:
·Potatoes can be boiled and peeled 1 day ahead and chilled, covered.
·Vinaigrette can be made 2 hours ahead and kept at room temperature.
·If you aren't able to grill, potatoes can be cooked in a well-seasoned ridged grill pan over moderately high heat, turning, until grill marks appear, 3 to 6 minutes total.
