All kinds of delicious stuff happens we you have awesome seafood stock in the freezer. I’ve been cooking sous vide for years. In the early days I’d find any reason to use my immersion circulator to cook anything. It was new to me and very cool. Now, I still use it a lot (and it is still cool) but not everything goes in the water container to be precision cooked. Sometimes it makes more sense to pan fry or roast or simmer a dish. One of the preparations that might seem ill-suited for sous vide is making stock. I agree that making beef, pork or poultry stock sous vide is not a great idea, a good pressure cooker (the opposite of the lower heat sous vide!) is best for that.
For seafood stock though, using my immersion circulator makes a fantastic brew. The idea to use sous vide for seafood stock is from Modernist Cuisine and it makes sense. Seafood and fish stocks need a gentle lower heat than other types of stock. So, bagging the protein (I routinely freeze shrimp shells and fish bones and save them up to make the stock) with a bunch of vegetables, a vermouth or white wine reduction and some herbs results in a deeply flavored, concentrated and clear stock of amazing quality. Another stock that benefits from this treatment? Vegetable stock also from the good folks of Modernist Cuisine. After straining, I package the stock in FoodSaver bags and freeze flat until ready to use in soup, risotto or paella.
Apparently chorizo is not supposed to be in a proper Spanish Paella as I recently read in a Saveur article. It’s too strong. It overpowers the rest of the dish. You lose the delicate notes of Saffron, paprika and seafood…I do not give a crap says I. I actually made this paella because I had a link of homemade dry-cured Spanish chorizo that needed to be used up and a good stash of the aforementioned seafood stock.
I’m also betting that the articles author might not like me using halibut much in this dish. It’s what looked best at the store when it came to white firm fleshed fish. Since the halibut is in nice thick pieces it held its shape very well, remained juice and ended up with a nice flavor and excellent texture. The first step is to sear the fish on the Paella pan to get some good color on the fish. After that I sautee chopped garlic and grated tomatoes along with smoked paprika in a good helping of olive oil.
Meanwhile, I added saffron threads to the seafood stock and let it infuse. When the garlic-tomato base was ready I added the chorizo and the rice. This got tossed really well and then I added the stock. A Paella is not risotto. The goal is not a creamy soupy rice dish. It’s not a pilaf either where you get a drier but still “steamy” rice dish. Paella is a dry rice dish, it is cooked with no stirring as the stock gently simmers away and the bottom browns and forms the much sought-after Socarrat.
When the rice is 90 percent cooked through I added garlic-marinated shrimp, roasted peppers and the seared fish for everything to finish cooking. That takes a few minutes and then I covered the whole pan up with aluminum foil to make sure the rice is fully cooked and the stock is all absorbed. A good aïoli is very strongly recommended with this. The easiest way to make this garlic flavored mayonnaise? A stick blender and narrow container, I make mayonnaise no other way and I’ve posted about it before here.
This was delicious and beautiful. Paella is another one of those dishes that I always wonder why I do not make it more often every time I cook a batch up.
