Water with a pinch of salt (Best Option)
1 cup water + 1/8 teaspoon salt per 1 cup vegetable brothWater is the primary hydrating agent in pizza dough and is essential for gluten formation and yeast fermentation. Adding a pinch of salt replicates the salt content typically found in vegetable broth, ensuring the dough's flavor and fermentation environment remain balanced.
When using this substitute, ensure the salt is evenly dissolved before mixing to avoid localized salt concentrations that can inhibit yeast. Monitor dough hydration as water lacks the minerals found in broth, but this difference is minimal in pizza dough.
The final crust will have a clean, neutral flavor similar to using vegetable broth, with no unintended flavor notes, allowing the toppings and sauce to shine.
