[Request] Sauces that would go well with lightly cooked salmon?

I'm cooking salmon in the oven until the fat between the layers starts loosing up (maby there is a culinary term in english, yet I only know it in my native language). So its nice, moist and creamy, not so dry and not so spongy as with frying or porching. What sauce would go well with salmon prepared in that way? I'm thinking of serving it with israeli couscous.

bon appetit
