Oh for sure, it's not an every day food. It's a treat. Because it's a bit heavier, I doubt I'd want it more than once a week. But yeah, I got two meals out of it between the okara and pumfu, with the pumfu one being kinda decadent. But as far as economics go, nothing's ever gonna beat gluten flour or dried whole beans.
But absolutely you'd have to watch out for rancidity with seeds. That's why I said it's probably not worth getting more than a 5lb bag, unless you have a chest freezer and are going to be freezing the seeds to preserve, at which point you're just paying back your bulk savings with the electric bill.
The two types of non-soy tofu I see at wholefoods are pumfu, which we've discussed, and chickpea tofu. The chickpea tofu, I believe is usually Burmese Tofu. Which if you haven't had that, it's suuuper different. It's somewhere between polenta and tofu. It's starchy because they use whole chickpea flour, not separated curds. BUT if you like that, it's extremely easy and economical to make at home, because you just stir water and chickpea flour (aka gram flour or besan) in a pot until it congeals, then let it set in the fridge.
You can make chickpea tofu that's more like what soy tofu is, but I don't think that's what you usually find in the market.
Yeah, if you can manage to just buy the gluten flour, it makes it soooo much easier. It really lowered the effort threshhold to where I make it more often.
