Tamari (Best Option)
1:1 (replace soy sauce volume exactly)Tamari is a gluten-free soy sauce variant that retains the umami and salty profile essential for flavor enhancement in scones. Its similar viscosity ensures the dough's hydration remains consistent.
When using tamari, measure it exactly as you would soy sauce to avoid altering moisture levels. Because it is less salty than some soy sauces, taste the dough if possible and adjust salt slightly if needed.
The final scones will have a comparable savory depth and balanced texture, making tamari the most seamless substitute in this context.
