Origin of Family words

[ihavesunshine]

My family and I have been brainstorming and we've come up with a few more! Thank you everyone for all the help so far. I would love to know the French-root of these words:

sackafrydough >> a nickname for beignets?
something like "ee-fod" >> when food lacked enough seasoning
John Sought >> what you got called when you had a brainless moment (like a Blonde moment). I cannot find any references to this on the internet!
No-ca-yo's >> bunions ?
gratin >> food stuck on the bottom of the pan

Thank you again!
