Yes, blending paste with broth instead of water can significantly enhance the flavor profile of your dish, adding depth and richness.
When a recipe calls for blending a paste, such as tomato paste, curry paste, or miso paste, using water is the standard approach. However, substituting broth (chicken, vegetable, beef, or even seafood broth) introduces a layer of savory complexity. The broth's inherent flavors infuse the paste, creating a more nuanced and flavorful base for your recipe. This technique works particularly well in soups, stews, sauces, and braises. The broth not only helps to thin the paste for even distribution but also contributes its own unique characteristics to the overall taste. For example, using chicken broth with tomato paste can add a subtle umami note, while vegetable broth can enhance the earthy tones of a curry paste. Experiment with different broth and paste combinations to discover your favorite flavor pairings.
If using a concentrated broth or bouillon cube, be mindful of the salt content. Reduce or eliminate any additional salt called for in the recipe until you've tasted the final dish, as the broth may already provide sufficient seasoning.
