Whisk all peanut sauce ingredients in a bowl (minus the water), then add water to thin to desired consistency.
For the curry sauce:
In a medium saucepan over medium heat, cook curry paste, sugar, coconut oil and halved garlic cloves and cook until garlic is fragrant but not browned. Slowly stir in coconut milk, lime leaves, and Thai basil and cool until heated through and curry paste is incorporated into the sauce.
Strain before serving.
To serve, add half peanut sauce and half curry sauce into individual dipping bowls. Garnish with crushed peanuts and enjoy with spring rolls!
