The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- White onions
- Boiling softens them, and frying with the steak adds browning and sweetness.
- Porterhouse steak
- Provides the main protein; searing in a hot pan browns its surface and builds flavor.
The step that matters
Cook the steak for 6 minutes on each side. Steak thickness and pan heat decide doneness. A pan that is not hot enough steams the meat instead of searing it, so the surface stays grey and the interior can overcook before browning develops.
