I'm trying a handful of vegan dishes, and have found a broth recipe which requires a small amount of soy or rice protein powder (1Tbsp). This eventually makes 30 cups of broth, so overall is a very small component.
I have wheat gluten available, and am wondering if it would be an acceptible substitute; or if I would be better off leaving it out altogether, or with another substitute (presuming the protein is used to slightly thicken the broth, would corn starch be a 1:1 substitution)?
