Tamari (Best Option)
1 teaspoon per 1 tablespoon soy sauceTamari is a gluten-free soy sauce variant with a similar salt and umami profile, making it ideal for maintaining flavor without altering dough hydration significantly. Its thicker consistency compared to regular soy sauce helps prevent excess moisture absorption in the pie crust dough.
When using tamari, measure precisely as it can be slightly saltier than soy sauce. Incorporate it evenly to avoid localized wet spots in the dough.
The final pie crust will have a comparable savory depth and flaky texture, closely mimicking the original recipe's balance.
