While the sauce is simmering, add the fresh figs, cut into quarters (or halved if they are small).
Let them just warm through and caramelize slightly in the sauce, without overcooking them so they retain their shape.
You can also set aside a few raw figs to add at the last minute when serving, for a touch of freshness.
Notes
You can serve these duck breasts with fig sauce alongside potatoes or green beans, either steamed or sautéed (you can use the duck juices or duck fat for this!).
