With the Anova Sous Vide Precision Cooker, you get perfect prime rib every time (which for us means, medium rare), with less than an hour of active cooking time. To ensure consistent seasoning, we dry rub the roast for at least an hour before the bath, and then finish with a festive multi-color peppercorn crust and 15 minutes in a hot oven to create a crispy, golden brown crust. The beef cooking liquid is combined with rich homemade beef stock to create an amazing beef jus.
