Flank Steak au Jus

with Creamy Dijon Cauliflower, Pickled Baby Turnips & Watercress

Au jus is a French culinary term for “with juice,” usually referring to meat served with its own juices as a sauce. It’s important to let steak rest after cooking it to allow the juices to redistribute, and often a little juice comes out in the process. That mixes with the deglazed “fond,” or brown bits at the bottom of the steak pan. Together with the addition of a little water, they become a sauce.
