A dry rub or spice blend? That’s a different story. No acid, no liquid. You can leave that on for up to an hour.
The spices will penetrate the surface without turning the flesh to mush. Paprika, cumin, brown sugar—they’ll form a gorgeous crust. Just don’t go overboard with salt. Your heart will thank you.
For a dry rub, rule of thumb: 30 minutes to 1 hour. Any longer, and the salt starts doing its moisture-sucking thing again.
The Temperature Check
Always marinate in the fridge. Not on the counter. I know it’s tempting to let it sit out, but bacteria love a party, and you don’t want that guest.
Take the salmon out 15 minutes before cooking to take the fridge chill off. That helps it cook evenly. But don’t let it sit out for an hour—safety first, drama second.
And please, don’t reuse the leftover marinade as a sauce. It’s got raw fish juice. That’s a one-way ticket to stomach regret. Make extra marinade instead, and keep it on the side.
