Vegetable Broth (Best Option)
1 cup vegetable broth per 1 cup beef brothVegetable broth works well because it mimics the liquid volume and savory flavor profile of beef broth, contributing to yeast activation and dough hydration. The umami compounds from vegetables like mushrooms and onions support flavor development in the focaccia.
For best results, use a low-sodium vegetable broth to control salt levels and avoid overpowering the dough. Warm the broth slightly before mixing to optimize yeast activity.
Compared to beef broth, vegetable broth produces a slightly lighter flavor but preserves the essential moist crumb and tender texture expected in focaccia.
