Don't stop with shrimp: This sweet and sour barbecue sauce promises to be a summer staple, since it's great on grilled pork chops and chicken too.
Heat a grill to high (450° to 550°). In a medium saucepan over medium heat, cook rhubarb, ginger, garlic, hoisin, sugar, and 1/4 cup water. When rhubarb starts to break apart, about 3 minutes, whisk in soy sauce and transfer half the glaze to a small bowl.
Thread shrimp onto 4 metal skewers. Brush both sides of shrimp with glaze from pan. Grill shrimp, turning and basting generously as you go, until they're opaque and grill marks appear, about 8 minutes total.
Transfer to a serving plate and brush with glaze from bowl. Sprinkle with onion. Serve with remaining glaze from bowl on the side.
Delicious and easy. Will make again!
This is excellent! Served with a Mango Noodle Salad.
