Decide what matters most: closest color, closest mild flavor, or no-fuss convenience.
Use the ratio from the list: for color-first swaps, start slightly low so you can adjust without over-darkening.
Stir the substitute into your warm base (or whisk into a marinade) so the color disperses evenly.
Taste after 1–2 minutes of simmer (if cooking) or after resting for 5 minutes (if no-cook), then fine-tune with a tiny amount more.
If the swap tastes bitter or too smoky, dilute with a neutral oil or water/broth to bring flavors back into balance.
