โญ Vegetable Broth (Best Gluten-Free Option)
1:1 (1 cup vegetable broth per 1 cup chicken broth)Vegetable broth contains similar water content and savory compounds as chicken broth, making it an excellent plant-based alternative. The umami and saltiness help replicate the flavor profile essential for biscuits. From a food science perspective, the broth's water content hydrates the flour, while the salts strengthen gluten formation, aiding in biscuit rise and flakiness.
For best results, use low-sodium vegetable broth to control salt levels and avoid overpowering the dough. Warm the broth slightly before mixing to ensure even hydration. Avoid broths with strong herb or spice flavors that might dominate the delicate biscuit taste.
Compared to chicken broth, vegetable broth produces biscuits with a slightly different but still savory flavor. The texture and rise remain largely unchanged, making it the closest substitute in both function and taste.
