Decide whether you need morita for smoky depth (smoke-forward) or for fruity warmth (mild-to-medium).
Choose the closest match from the table: chipotle for smoky heat, ancho/guajillo for fruity warmth, or cayenne + smoked paprika for a pinch.
Use the listed ratio; if your substitute is hotter than morita, reduce by 25–50% and build gradually.
If the substitute is ground (ancho/guajillo/powders), bloom it in a teaspoon of oil for 30–45 seconds to rehydrate flavor.
Taste at the end and tune: add a little acid (lime) if it reads flat, or add more chili if it lacks warmth.
