Instructions
Serves 2-4 Level of difficulty 3
Procedure:
Seal the flat iron steak/roast in heat rated sous vide bags and process at 129 F/54 C X 6+ hours. This will pasteurize and tenderize the protein. Shock cold in iced water until the package achieves 70F/21 C. Refrigerate at 40 F/4 C until day of service. Cold shocking prevents autolysis in the steak, and also protects other foods in the refrigerator from temperature contamination. In this state, the steak/roast can be refrigerated for up to two weeks without any deterioration..Day of service
Submerge the package in hot tap water (110 F/43 C) or a working sous vide bath to melt the gel in the package. Remove the roast from the package and stage onto a rack to drain.





While you wait
Make the coleslaw as explained HERE. We left the roasted corn out of today's model. Refrigerate. Mushroom sauce: Heat the 2 Tablespoons of oil in a skillet to 300 F/150 C. Turn off the burner and add the 2 Tablespoons of flour--it should foam immediately and will appear thin. DO NOT BROWN.
