โญ Rice Vinegar (Best Gluten-Free Option)
1 tablespoon rice vinegar per 1 tablespoon lemon juiceRice vinegar is a mild, slightly sweet vinegar that closely mimics the acidity level of lemon juice without introducing harsh or overpowering flavors. Its gentle profile complements the soy sauce and sugar base, maintaining the characteristic tang and brightness of teriyaki sauce.
When substituting, use an equal amount and taste as you go to ensure the acidity level suits your preference. Avoid overuse to prevent the sauce from becoming too sharp or vinegary.
The final sauce will retain its traditional flavor profile with a slightly different acidic note, but overall the balance between sweet, salty, and sour remains harmonious.
