I cook all my meat in the slow cooker ..no water !!
Leg of lamb just cut slits in the joint ..stuff slivers of garlic and sprigs of rosemary in the slits.Sprinkle dried rosemary over it if you have no fresh.Plonk it in the cooker and cook overnight on low or six hours on medium ..will fall off the bone.
Chicken ..the same ..shove a lemon up his bottom and plenty of garlic ..rub a bit of butter and black pepper on his breast plonk him in and cook on medium for six hours ....tender and juicy.
Brisket ..plonk it in and cook six to eight hours on low for a large piece..you don't need any water the meat will release enough juices for gravy.When you take the brisket out you can make the gravy from the juices left in the pot ..I do this with a hand blender .
I dont know about putting them in the oven ...mine is an earthenware pot ..I also have the Morphy Richards one ..the 6.5 litre.
I add potatoes towards the end of cooking or dumplings for a casserole ..they will cook quite quickly too as by then your pot is well up to temperature.
Although I have used a slow cooker for donkeys years you can always find new ideas for them and this book is excellent .In fact I made a cake in it recently from a recipe in this book and it was lovely.
