Being friends with several Americans I've come to realise our eating habits are very different.
Back in the '50s, any sundae was a DIY project, usually a simplified version of the soda fountain creation. My father made his with store brand vanilla ice cream, ditto chocolate sauce and salted redskin peanuts.The Tin Roof Sundae is a standard flavor in many of our "boxed" ice creams
we get from a "large" stores like Aldi or Food Lion, big stores that
carry pretty much everything..
