Red curry paste conveys plenty of spicy heat, so a little goes a long way. Feel free to add a bit more to increase the heat, or omit the paste to tame the dish. The addition of slightly sweet coconut milk smooths out the flavors.
1. Heat oil in a large nonstick skillet over medium-high heat. Add onion and curry paste to pan, and sauté 1 minute, stirring occasionally. Stir in sugar; sauté 15 seconds. Add shrimp; sauté 3 minutes or until shrimp are done, stirring frequently. Stir in coconut milk and fish sauce; cook 30 seconds or until thoroughly heated. Remove from heat; stir in green onions and basil.
