Choose your substitute based on recipe needs: dry for toppings like mushroom powder or sesame seeds, wet for sauces like miso paste.
Prepare the substitute accordingly: toast mushroom powder or sesame seeds, finely grate Parmesan, or grind sunflower seeds.
Apply substitute using recommended ratios: generally 1 tablespoon substitute per 1 tablespoon nutritional yeast, adjusting salt and liquids as noted.
For wet substitutes like miso paste or soy sauce, reduce other liquids by the specified amount to maintain recipe consistency.
Add salt gradually when using salted substitutes, and taste-test to avoid oversalting.
In hot dishes, add Parmesan off heat to prevent clumping and preserve texture.
Blend substitutes into finer textures if the recipe requires smoothness, especially for sauces or dressings.
