Choose the substitute closest to your dish: a celery-salt-based blend for seafood, or a peppery paprika blend for snacks and chicken.
Start with the listed ratio (often 1:1 or ¾:1), then taste the seasoning against the base—especially for saltiness.
If your substitute is less “celery-salty,” add a small pinch of celery salt or salt; if it’s hotter than Old Bay, reduce pepper/paprika next time.
For wet cooking (boils, sauces), bloom spices in the fat or warm liquid for 30–60 seconds before adding the main ingredients.
For dry use (fries, popcorn, rubs), apply slightly early so salt hydrates on the surface, then adjust with a final pinch after cooking.
