Baked Mackerel

We had a whole Mackerel in the fridge that needed to be cooked before it turned, so even though T was working all night, and I didn't get home until 8pm, I did something quick with it:

I mixed the juice of 2 lemons and the peel of one with 1 cup of pitted green olives and some olive oil and basil in a bowl, stuffed this mix into slits in the fish and baked at 350F for 30min, flipping after 20.

Ok, well to be more accurate, I at first put a meat probe in the fish which registered something like an internal temp of 190F at 20min (I was cooking it to 145F). So then I took it out, but it was clearly not done, so I flipped it and threw it back in for 10 more min, until it was more fragrant, and juices were spattering int he oven.

Next time I definitely need something like 2x the olive mix, but overall I was happy with it.  It was not too mackerelly in flavor.
