Instead of using milk in the batter for this pancake, I used a banana - soy smoothie (1 cup soy milk & 1 banana) which I soured with a tablespoon of vinegar — and instead of egg, I used a heaping tablespoon of okara. (222milliontons.com)
Your recipe should steam or bake / toast raw okara for 25 to 45 minutes and cool before using, to make the proteins more digestible and remove undesirable enzymes. (ellenskitchen.com)
For the «ricotta» I used okara instead of tofu, and added a bit of wasabi (you can tell I live in Japan here...) and white wine to give it some kick. (hungryhungryhippie.com)
