Make an extra-bright sauce by adding more lemon juice. In the mood for a fiery kick? Hopper suggests adding more chile-garlic sauce, as in this recipe, balanced with soy sauce for added depth.
This is a very hot sauce and good for splashing over anything ... Place the chillies in a saucepan, add the garlic and 700ml/1¼ pint water. Bring to the boil and simmer for 15 minutes.
