Select the substitute based on your dish and desired flavor profile, whether you want the numbing effect or just citrus brightness.
Prep the substitute by blending, mixing, or zesting as indicated for the specific ingredient combination.
Measure and apply the substitute according to the recommended ratios, adjusting seasoning as needed to taste.
Add citrus ingredients toward the end of cooking or as a finishing touch to preserve aroma and flavor.
Check the final dish for flavor balance, ensuring the heat, citrus, and numbing effect (if desired) are to your liking.
