This is a good recipe and my only complaint is that the recipe doesn't specify the actual amount of lemon and lime juice in the sauce. If a lemon/lime is large or juicy, it will be very sour, even with straining out all of the pulp and seeds. I ended up adding additional maple syrup and miso, tasting as I went along.
The flavor of the miso sauce in this recipe is really delicious. Be careful: I think I put the salmon too close to the broiler because it burned around the edges. Next time, I'll cook it on the next level down.
