Water with a pinch of salt (Best Option)
1/4 cup water + 1/8 teaspoon salt per 1/4 cup vegetable brothWater is the neutral base that provides the necessary hydration for binding ingredients in granola. Adding a small amount of salt mimics the slight seasoning vegetable broth provides without introducing conflicting flavors.
When using this substitute, ensure the salt is well dissolved and evenly distributed to avoid salty pockets. Avoid adding too much salt as granola is typically a lightly sweetened product.
This substitution results in a granola very close to the original in texture and flavor, with no savory notes that could detract from the sweet and nutty profile.
