FAQ
What temperature for marinated steak?
131°F (55°C) for 2-3 hours — tender and juicy.
Do marinades penetrate deeper with sous vide?
Yes — the long cook time drives flavor further in than a quick pan sear.
Should I pat the marinade off?
Yes — dry the surface before searing or you'll steam, not sear.
