Identify how your recipe uses garlic powder: dry rub/dredge (needs dry granularity), sauce/marinade (can handle moisture), or finishing (focus on aroma).
Pick the closest substitute from the table: garlic granules for a dry 1:1 swap, or fresh minced/roasted paste when moisture is already in the dish.
Apply the listed ratio, then adjust for salt (garlic salt) or intensity (fresh garlic is typically stronger).
If using fresh garlic, sauté briefly in fat or cook it briefly before the dish to avoid raw harsh notes.
Taste after the recipe’s key cooking step (or after simmering 2–5 minutes) and fine-tune with an extra pinch of the chosen substitute.
