Put peanuts, chili and garlic in a
blender. Mix together, then add curry paste,
2 tablespoons of coconut milk and a squeeze of lime juice. Mix to blend evenly. Pour mixture into a saucepan. Stir in remaining coconut milk and
sugar. Bring to the boil, stirring then
boil for 2 minutes. Lower heat and simmer for 10
minutes, stirring occasionally. Add a little water if sauce becomes
too thick.
