⭐ Soy Sauce with a Touch of Brown Sugar (Best Nut-Free Option)
1 tablespoon soy sauce + 1/4 teaspoon brown sugar per 1 teaspoon vanilla extractSoy sauce is rich in umami compounds that deepen the savory flavor profile of stir-fry dishes. The addition of brown sugar mimics the mild sweetness vanilla extract would add, balancing the salty and savory notes.
To ensure success, dissolve the brown sugar fully in the soy sauce before adding it to the stir-fry to avoid graininess. Adjust sweetness to taste depending on the other ingredients.
Compared to vanilla extract, this substitute shifts the flavor toward savory and umami rather than floral sweetness, which is more appropriate and harmonious for stir-fry dishes.
