β Water with a pinch of salt and a teaspoon of nutritional yeast (Best Fat-Free Option)
1 cup water + 1/8 tsp salt + 1 tsp nutritional yeast per 1 cup vegetable brothThis substitute works because water provides the necessary hydration for gluten development and yeast fermentation, while the salt enhances flavor and the nutritional yeast adds umami that mimics the complexity of vegetable broth. Nutritional yeast is inactive and will not interfere with yeast fermentation.
For best results, dissolve the salt and nutritional yeast fully before mixing into the dough to ensure even flavor distribution. Monitor dough hydration as nutritional yeast may slightly thicken the liquid.
Compared to vegetable broth, this substitute yields a clean flavor with a mild savory note, preserving the breadβs rise and crumb structure without introducing unwanted fats or sugars.
