Left shiitake mushrooms in water overnight and left them braising in the slow cooker all day with garlic, ginger, onion, carrots and yellow peppers, Chinese rock sugar (which i bashed with a mortar and pestle) some leftover chicken and chicken stock. Served this evening with glass noodles. Big meaty mofos were these mushrooms! Apparently some of the healthiest things you can eat, I can understand some folks fear about them (not everyone ate them, so they had supernoodles instead) .
