Can I use a different cut of steak instead of picanha?
Yes. Ribeye, New York strip, or filet mignon work well. Adjust cooking time based on thickness and desired doneness.
What's the difference between black and Sichuan peppercorns in this sauce?
Black peppercorns provide sharp heat and classic pepper flavor; Sichuan peppercorns add a citrusy, numbing tingle for complexity.
How do I know when the steak is done?
Use a meat thermometer: 120–125°F for rare, 130–135°F for medium-rare, 140°F for medium. Rest for 5 minutes after cooking.
Can I make the peppercorn sauce ahead of time?
Yes. Prepare the sauce up to 2 hours ahead and reheat gently over low heat, whisking in butter just before serving to restore creaminess.
What can I substitute for cognac?
Brandy, bourbon, or dry white wine work as alternatives. Use equal amounts but adjust cooking time to burn off alcohol.
