Shrimp-Boil Kebabs

In a medium pot, bring potatoes to a boil in salted water over medium-high. Reduce heat and simmer until potatoes are tender when pierced with a knife, about 12 minutes. Drain and rinse under cold water. Alternately thread potatoes, corn, andouille, and shrimp onto four 8-inch skewers.

Heat a grill to medium-high. Clean and lightly oil hot grill. In a small bowl, combine butter, hot-pepper sauce, and Old Bay Seasoning. Grill kebabs, turning and brushing with butter mixture occasionally, until shrimp are opaque throughout and corn is tender and beginning to char, about 8 minutes. Serve with lemon wedges.
