Vacuum bluefin tuna


First experiment with low temperature cooking. A few days ago we explained what it is and how it works A domestic vacuum cooking machine. Ours is a Anova But there are many different brands in the market. They are not especially expensive (it depends on the functionalities) and with an offer you can get one for just over € 100.

I will say that we opt for tuna because Ro and I always complain that it is very complicated to give the exact point to the meat. At home or in any restaurant or they are left dry or raw. Wow, we have risked in the first test but I will say that despite my skepticism, the bluefin tuna fillets have been perfect. The beginner's luck? Maybe but I've looked so good in front of Ro :-)

The recipe is a free adaptation of the original of Vacuum Tuna of the App of Anova which for my taste has an excessive load of pepper and oil. If you put too much black pepper, it will sting and you will not enjoy the original taste of the fish. Watch out!

In this photo I show you the result of the tuna already made, out of the bag and without going through the pan to mark it. Behind you can see another packaged and uncooked piece - ready for the next recipe. The appearance is surprising. It looks like a piece of beef. Be very careful and do not handle it as if it were a ribeye because it is more fragile and can be opened. And that has no arrangement.

A steak came to spare for both of us and the second we have frozen for another day. Be careful because the thickness directly affects cooking times. In the recipe I have set average cooking times but if you like almost raw inside, do not exceed 43 degrees of water temperature in cooking. If you are beginners like us in this of sous vide cooking, you will have to visit a blog in Spanish of low temperature cooking, it is from Cris and Xavi and it is great “At low temperature”, I leave it here.

I also advise you to go to the fish market and ask for quality pieces. The low temperature cooking greatly enhances the flavors and a good fish you will enjoy much more.
