For milk it’s more 60g per litre so you’d have 15-20 litres per kg of beans - more than that and it’s very thick.
We leave the okara inside often when cooking but otherwise we filter it out with a cheese cloth on the side - but it’s drinkable unfiltered just a bit grainy. And we just compost it when we do throw it away.
Tbh we only use it to make nut milks and soy milk, but I’ve made soup once or twice with it. I don’t think it’s its best use however.
That’s amazing lol if you’re anything like us you will cherish it every day.
