Sous vide is
a French phrase that is translated as “under vacuum.” However, the defining
feature of the method is not packaging or vacuum sealing; it is accurate
temperature control. A heating element can warm a water bath to any low to
moderate temperature you set, and keep it there for hours – or even days. For
more information on the how’s and whys of sous vide, please see post: All About
Sous Vide at http://cookingwithlarue.blogspot.com/2015/06/all-about-sous-vide.html.
Sous vide is
especially useful for cooking seafood, for which the window of proper doneness
is often vanishingly small when traditional methods are used. When you fry a
piece of fish, the flesh is most succulent and tender within a very narrow
temperature range. Because the cooking temperature of the pan is considerably
hotter than the ideal core temperature of the fish, the edges will inevitably
be far more cooked than the center when pan-fried. Traditional cooking with a range,
oven, or grill uses high and fluctuating temperatures, so you must time the
cooking exactly; there is little margin for error. With just a moment’s
inattention, conventional cooking can quickly overshoot perfection. This is
particularly problematic with fish…especially lean fish, which can dry out
quickly. Sous vide cooking is ideal for such fish, in this case swordfish, but
also albacore.
Swordfish was taboo for a while, but now many varieties,
especially domestic ones, are sustainable. In particular, the North Atlantic
swordfish have really rebounded thanks to a 1999 international plan that
rebuilt this stock several years ahead of schedule.
