Sea bass with spinach, sesame and soy

Pesach is getting closer, and the freezer-emptying effort has been stepped up. There are no more sea bass fillets in my freezer! Now I just have the salmon and hake backlog to deal with…

Having defrosted them, I had to work out what to do with them. I do love a dish with an alliterative title, don’t you? And there was a big bag of spinach in my organic box, so that was a good start. A quick cupboard raid later, and this delicious recipe was born. (I hope the garlic forgives me for not including it in the title…)

I wanted to assemble everything up to the cooking stage, before going out for a couple of hours, so that I could throw it in the oven upon my return and it would be done by the time I’d taken my coat off, set the table, and pulled myself together. This recipe fit the bill nicely. The sea bass absorbed the flavours of the sesame oil, garlic and soy sauce for a couple of hours before cooking – sort of like a marinade, I suppose – and the end result was moist and flavourful fish. (Having experimented with the rate of diffusion of soy sauce through food, I’m pretty confident in saying that two hours probably don’t make much difference, so if you want to make this and then shove it straight in the oven, I expect it would be completely fine.)

The spinach looks like a lot pre-cooking, but as always with spinach, it almost disappeared once the dish was cooked. Kipper was initially reluctant to eat the spinach, but once she’d tried it and realised that it tasted of delicious garlicky soy sauce and sesame oil, she scoffed it down. And nearly a whole sea bass fillet, too. 

This served two adults and a small person. I’d say we could have seen off quite a bit more spinach too, had it been available.
