This is the perfect condiment for our Tandoori-Style Chicken.
In a medium skillet, heat oil over medium-high. Add onion and cook, stirring occasionally, until soft, 6 minutes (do not let brown). Season with salt and pepper. Add apricots and 1/2 cup water; cook until apricots soften and onion begins to brown, about 5 minutes. Add vinegar, marmalade, and ginger; cook, stirring occasionally, until liquid is syrupy and apricots are plump, 3 to 5 minutes. Season to taste with salt and pepper. (To store, refrigerate in an airtight container, up to 2 weeks.)
