1. Heat grill until very hot. Place rice and 1 3/4 cups water in a small saucepan, and bring to a boil. Reduce heat to low, and simmer, covered, about 20 minutes. Let sit 5 minutes, fluff with a fork, and let cool.

3. Leaving tails intact, peel and devein shrimp; transfer to a medium bowl. Add remaining 1/2 tablespoon olive oil and curry powder. Toss until shrimp are well coated. Thread shrimp onto skewers, and place on hot grill. Cook until pink and opaque; serve over rice.
