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 vegetable broth, so it preserves the dough's moisture content. Adding a pinch of salt mimics the slight seasoning present in broth, which helps maintain yeast activity and dough flavor balance.
Ensure the salt is evenly dissolved to avoid localized salty spots that could affect yeast fermentation. Use filtered or distilled water to avoid off-flavors.
The final cinnamon rolls will have a clean, neutral base flavor similar to using vegetable broth, allowing the cinnamon and sugar to shine without interference.
