Buying advice
Cook ribeye, strip, and other well-marbled steaks at 137°F for 2-3 hours — the fat renders silky instead of waxy, and it's still medium-rare-plus. Lean cuts (filet, sirloin) stay at 131°F — they have no fat to render. This one number is the biggest flavor upgrade in sous vide steak.
FAQ
Why does my ribeye fat taste waxy?
It never got hot enough to melt — beef fat needs ~137°F. Your 131°F bath left it solid.
Is 137°F still medium-rare?
It's medium-rare to medium — the fat makes it taste juicier than the number suggests.
What about the lean cuts?
Filet and sirloin stay at 131°F — no fat to render, and higher temps would dry them.
