Water with Soy Sauce and Spices (Best Option)
1 cup water + 1 tablespoon soy sauce + 1/4 teaspoon turmeric + 1/4 teaspoon ground cuminThis substitute works because soy sauce provides glutamates that mimic the savory depth of vegetable broth, while turmeric and cumin add aromatic complexity essential to curry. The water dilutes the intensity, keeping the balance similar to broth.
For best results, dissolve the soy sauce and spices fully in hot water before adding to the curry. Adjust soy sauce quantity to avoid excessive saltiness.
Compared to vegetable broth, this substitute maintains the curry’s savory backbone and spice profile but may lack some subtle vegetal notes, which can be compensated by fresh herbs or additional spices.
