Pure umami flavor enhancer that deepens savory taste in any dish without adding distinct flavor of its own.
Substitutes
Mushroom — 1 tsp mushroom powder per 1/4 tsp MSG. Dried mushroom powder is rich in natural glutamates that provide the same umami boost as MSG. Use about 4 times as much to achieve equivalent savory depth.
Soy Sauce — 1/2 tsp soy sauce per 1/4 tsp MSG. Soy sauce is naturally rich in glutamates from fermented soybeans. It adds umami along with saltiness and color, so reduce other salt in the recipe.
Fish Sauce — 1/4 tsp fish sauce per 1/4 tsp MSG. Fish sauce packs intense umami from fermented fish. A few drops deliver powerful savory depth similar to MSG, but with added complexity and salt.
Nutritional Yeast — 1 tsp nutritional yeast per 1/4 tsp MSG. Nutritional yeast contains natural glutamic acid that provides cheesy, savory umami. A popular plant-based umami source, though it adds a slight yeasty note.
