I winged this recipe but here is what I did. Sliced orange under the salmon, coated the salmon with olive oil, salt and pepper and topped the salmon with sliced orange.
Baked in a 350~ oven for 20 minutes.
I made my fool proof hollandaise recipe which is Julia Childs recipe and you can find it here. Instead of adding the cayenne pepper I added a tablespoon of the spice blend here, 2 tablespoons orange juice and 1 tablespoon lemon juice.
This was (as I said) a rescue, if any of our members have leftover spice blend I highly recommend adding it to hollandaise. If you just want an amazing hollandaise sauce skip the blend and just add orange zest, orange juice, lemon juice and real chili powder or 1 pureed chipotle.
