Choose your substitute based on the dish type and desired flavor match. Use chickpea miso or rehydrated powder for authentic miso depth; use the soy-sugar blend or tahini mix for quick dressings and sauces.
Prepare the substitute as directed: whisk compound blends smooth before adding, rehydrate miso powder with equal parts warm water, or use chickpea miso paste directly from the container.
Apply the substitution ratio carefully. Start with the stated amount and adjust to taste, as some substitutes are significantly saltier per tablespoon than white miso paste.
Taste and adjust seasoning at the end of cooking. Hold back on added salt until after the substitute is incorporated, then fine-tune as needed.
