Directions
Using a sharp knife, peel the limes, removing all of the bitter white pith. Working over a bowl, cut in between the membranes to release the sections into the bowl. Finely chop the sections.
Heat the oil in a large saucepan.
Add the curry powder and stir over low heat until fragrant, about 5 minutes.
Add the chopped lime and lime zest and cook over moderately high heat until the juices have evaporated, about 5 minutes.
Add the sugar and stir until melted.
Add the scallions and cook, stirring, for 2 minutes.
Add the coconut milk and boil over moderately high heat, stirring often, until reduced to 2 1/2 cups, about 15 minutes.
Let cool, then season with salt.
Transfer to jars and refrigerate.
Make Ahead: The sauce can be refrigerated for 1 month.
