Fe Fi For Fum... I'll Grind His Bones To Make My Bread.

[sandyRoe]

Were animal bones ever used in the making of bread? I can't see a time when human bones were used.

[jno]

common practice among giants, but as far as I know it's been frowned on in intra-human cuisine.

I note that Wikipedia says:
Charles Mackay proposes in The Gaelic Etymology of the Languages of Western Europe that the seemingly meaningless string of syllables "Fa fe fi fo fum" is actually a coherent phrase of ancient Gaelic, and that the complete quatrain covertly expresses the Celts' cultural detestation of the invading Angles and Saxons:

Fa from faich (fa!) "behold!" or "see!"
Fe from Fiadh (fee-a) "food";
Fi from fiú "good to eat"
Fo from fogh (fó) "sufficient" and
Fum from feum "hunger".

Thus "Fa fe fi fo fum!" becomes "Behold food, good to eat, sufficient for my hunger!"

I believe that ground animal bones were once used to adulterate flour.

I've never heard of bones. The Victorians put plaster of paris in bread.

[naomi24]

In the 1500s starving Parisiennes ground human bones to make bread - allegedly.

Fe Fi phobia is the fear of Giants

Maybe they thought that by adding yeast they could raise the dead.

Yes, somewhere from the mists of History lessons, the 'Adulteration acts' were introduced to ensure that traders did not water milk etc. Plaster was frequently used in flour, but so were ground bones. I wish I could remember more. I do remember some of the additions were fairly horrible.
I'm fairly sure that 'baker's dozen' came from about the same time - so they could not be accused of short-changing their customers.
Best I can do without some research.
