Shrimp & Crab Bisque Sous Vide

Nowadays bisque is many things to many people. Currently most associated with shellfish it originally is said to have been a savory puréed soup of game birds. Whether it's fowl, vegetable or some deep sea creature I believe it's safe to say the final product is a rich intense creamy purée, that's damn tasty!
Other than the star ingredient another variable is how the bisque is thickened, recipes abound utilizing floury rouxs’ and/or copious amounts of rich cream. This recipe is following a more or less classic French style that uses rice as the primary thickener. Rice is a wonderful way to thicken as well as adding a velvety texture without extra fats. Cream is still used to finish the bisque but just enough to enhance and not overpower the shrimp and crab.
