⭐ Water with Soy Sauce and Tomato Paste (Best Nut-Free Option)
1 cup water + 1 tablespoon soy sauce + 1 teaspoon tomato paste per 1 cup vegetable brothThis combination works because soy sauce provides glutamates that replicate the umami depth of vegetable broth, while tomato paste adds acidity and richness that complement chili spices. The water dilutes the intensity, balancing the flavors.
For best results, dissolve the tomato paste fully in warm water before adding soy sauce to ensure even flavor distribution. Adjust soy sauce quantity slightly if the chili becomes too salty.
Compared to vegetable broth, this substitute maintains the savory backbone and acidity essential for chili, preserving the dish’s robust and layered flavor without introducing unwanted animal notes.
