โญ Water with a pinch of salt and a splash of lemon juice (Best Vegan Option)
1 cup water + 1/8 tsp salt + 1/2 tsp lemon juice per 1 cup vegetable brothVegetable broth primarily provides moisture and a mild savory background. Water alone lacks flavor, so adding a small amount of salt and lemon juice simulates the broth's subtle umami and acidity, which helps balance the sweetness of banana bread.
To ensure even flavor distribution, mix the salt and lemon juice thoroughly into the water before adding to the batter. Avoid adding too much lemon juice to prevent sourness.
This substitute preserves the moist texture of the bread and keeps the flavor profile close to the original, ensuring the banana's sweetness remains prominent without any unwanted savory or bitter notes.
