I'd like to make a Parmesan dashi for an "Italian ramen" dish I've been developing. I have a couple pounds of Parmigiano-Reggiano rinds and am curious if anyone has any ratios or time/temp settings to recommend. The final dish will have a broth made from white chicken stock, Parmesan, kombu, and dried porcini mushrooms, and will be topped with guanciale, lardo Iberico de bellota, and a 63C egg yolk. The hope is that the final dish will be somewhere between ramen and carbonara.
