I have had my slow cooker over 30 years and have never looked at/used their cookery book, just throw it all in and go.Sometimes I brown the meat & onion [in same pan] first but thats usually only when I realise after 4 hours I have forgotten to switch it on.If you make and put dumplings on the top for the last half hour they taste good.Oxtail chucked in the slow cooker onhgh with veg is really good but you have to take the fat off the top before you serve and you can chuck new potatoes in about half hour before its ready.easiest way to remove the fat is to put two layers of kitchen roll on top of the cooked food and let the paper soak up the fat, might have to do it a couple of times,but then caran you probably already know this, so pls dont think I am being cheeky.
