Veggie burgers that Bleed I have found these veggie burgers that bleed; but as we can see the price is hefty (~$62 for 5 lbs). I want to replicate them at home. They would have to be very convincing - ideally, the person eating them will not recognize that they ate a plant product and not meat without being told. 

What techniques and (vegetable-derived) ingredients can I use to imitate a real, bleeding meat burger?
The ingredient list on the commercial product already gives you several pointers to work with in building a recipe:


A legume protein is used, with additional binders (tapioca starch). Probably not in plain flour form, since that would result in more of a pancake than a meat like texture.
beet juice and paprika are used both for a reddish colour and to get some of the adstringency/earthyness of meat juice in there. Also, one can assume the end product to be relatively acidic (despite there being an alkali - potassium bicarbonate - present), otherwise beet juice would give you a blue off colour.
At least two layers of smoke flavor - mesquite powder, hickory smoke extract - are used
shiitake and yeast extracts - umami sources
an iron compound - probably not just for enrichment, iron-adstringency is a flavor component in meat taste...
