Chicken wings, which contain ample collagen, yield a rich, full-bodied broth. Use this as a base for passatelli en brodo, or in any recipe that calls for store-bought or homemade chicken broth. Store in an airtight container in the refrigerator for up to five days or freeze for up to a month.
Don’t forget to allow a 20-minute natural pressure release after cooking is complete. If the steam is released any sooner, the pressure remaining in the pot may cause liquid to spout out of the vent.
