I don't know how this is so difficult!
one chicken stew with chicken legs that completely disintegrated into individual fibres
one pearl barley stew (Hugh F-W's) which turned into lumpy glue
and both of them tasted of nothing! all the lovely veg etc I put in was totally annihilated
Each time I have left it on low all day and gone to work. That's how it's supposed to work, isn't it?
