Somebody mentioned walnut oil. Be careful about this, and some other oils, as there are some people who are very allergic to walnuts and could be adversely affected by even traces of walnut oil.

I know somebody for whom walnuts and sesame seeds (and their oils) are an very unpleasant experience. Her husband carries a vial of anti-allergic stuff whenever they go out – and has had to use it at least once.
