proimage is right, the "oil", otherwise known as shortening, is actually in solid form when it's at room temperature. it's a solid cake of almost claylike substance. it'll melt when heated and will look like regular cooking oil.
How old were you guys when you had your first bite? Could it be that your expectations have changed through the years?
I remembered when I was a kid, everything was bigger than life. Jeez.. I thought BigMacs was the best thing ever. But as I grow older, I get jaded, more affluent, discerning... well you get the idea.
So probably its not because the quality of the food has deteriorated, but we just got a little older... :think:
