Mornin' all, some questions about oil for you. First, is flax oil the same as linseed oil? I have a recipe for soyannaise which uses flax seed oil. If it is the same as linseed I really don't like the flavour and can't help thinking that the result will taste horrible. Why if they are the same is it referred to by two names? It also uses sunflower oil. My next question is, when a certain oil is stated how interchangeable is it with other oils? Eg what difference would it make if I used olive oil instead of the flax/linseed oil and rapeseed oil instead of the sunflower etc etc? Is it just taste or something else? I often do replace oils but it is very random and dependent on what oil I happen to have at the time.
