Vegetable Broth (Best Option)
1:1 (1 cup vegetable broth per 1 cup chicken broth)Vegetable broth mimics chicken broth's moisture content and savory profile, which is essential for pie crust dough hydration and flavor. The broth's mild vegetable flavors integrate well without overpowering the crust.
When using vegetable broth, ensure it is low sodium to avoid excess salt in the dough. Also, use a clear broth to avoid discoloration. Chill the broth before mixing to prevent premature gluten development.
Compared to chicken broth, vegetable broth produces a similarly tender and flaky crust with a slightly different but pleasant savory note, making it an excellent plant-based alternative.
