Porcini risotto with cavolo nero and cobnuts

Just a handful of dried porcini mushrooms is enough to add a wonderfully rich, savoury flavour to this risotto. The cobnuts complement the earthiness of the porcini as well as adding a bit of crunch, contrasting with the creaminess of the risotto rice. Cobnuts are cultivated hazelnuts and can be bought fresh in their husks and shells in late summer and dried later on in the year. If you have difficulty in finding them, opt for hazelnuts instead. This risotto also works with pearl barley. Si
