hi, I got a small swan 1.5l slow cooker for xmas, was so excited to try it out today but the beef stew has turned out really unappetising-I don't know whats gone wrong-I put in beef covered in some flour, carrots ,onions and a small amount of stock- the meat chunks all shrivelled up, the gravy was so watery I've had to reduce it down. the beef tasted ok but the carrots and onions were like I remember school dinners!it was put on low for 7 hours but I noticed it did seem to be bubbling a fair bit. the beef was only partially covered by the fluid. I don't want to give up yet! any tips would be great please!
