This creamy and rich sauce is based on a white veloute. A white veloute is one of the five “mother sauces” of classical cuisine. It can be made with any white stock, but this version is made with fish or vegetable stock.
As far as I am concerned, Halibut is the king of fish. Quickly pan seared, and served on a bed of wilted spinach, with a garnish of prawns, and asparagus, alongside a creamy white vermouth sauce. Yum! (this picture also has a cheffy smear of roasted squash puree on the side of the plate!)
