Choose your substitute based on the dish type and desired flavor match. Use lentils or TVP for baking, mushrooms or beans for moist sauces, and tofu crumbles for high-heat cooking like tacos and stir-fries.
Prepare the substitute as directed: cook lentils 15-20 minutes and drain; press tofu 15-20 minutes and crumble to pea-sized pieces; sauté mushrooms in a dry pan until browned; coarsely mash beans; rehydrate TVP in hot broth for 5-10 minutes and drain.
Apply the substitution ratio carefully. Start with the stated amount (1:1 for most; 2:1 raw for mushrooms) and adjust liquid in the dish by 1-2 tablespoons based on the substitute's moisture level.
Taste and adjust seasoning. Add umami boosters like miso paste, soy sauce, or nutritional yeast at 1 teaspoon per cup of substitute to deepen savory flavor where needed.
