As a youngster, I attended a boarding school for 5 years. There was no such 'animal' called margarine. I received my pint of full cream milk each morning and about a pound of butter per week. More than 50 years ago, full cream milk, was exactly that. About a third of the bottle of milk was cream. Unreal!
I hate the taste of margarine.

For years, I have used olive oil...not too much butter...lesser amounts of frying with sunflower oil. Try to saute your schnitzel with olive oil & a little butter...delicious.

All of the above is negated by my excess smoking & over friendliness with a certain Mr.J. Walker! ;) But, we carry on regardless!
