⭐ Tamari (Best Vegan Option)
1 tablespoon per 1 tablespoon of soy sauceTamari is a Japanese soy sauce variant that is typically gluten-free and has a richer, less salty profile than regular soy sauce. Its amino acid content provides the umami flavor essential for enhancing the focaccia dough’s taste without compromising yeast fermentation or dough structure.
When using tamari, maintain the same volume as soy sauce to keep salt and moisture levels consistent. Monitor dough hydration as tamari is slightly less salty, which may require minor salt adjustments.
The final focaccia will have a comparable savory depth and crust color, with no adverse effects on crumb texture, making it the closest functional and flavor match to soy sauce in this application.
