Glue

Let’s be honest here, flour and water is not so much a foodstuff as an adhesive.

It’s what you used to make a primitive type of glue when you where a pre-schooler. 

So following on from that starting point…

Bread = baked glue.

Pasta = boiled glue.

Yum yum*.

*Usage of the words “Yum yum” may indicate the author is employing extreme sarcasm. Glue is not tasty, and should never be eaten under any circumstances.
