For anyone who gets bored and wants to cheat I used a PHP script to scan through a free dictionary, and list all the 4-vowels. The results are here: http://semichrome.net/~cuvc/other2/out4.txt
It only gets one that we haven’t yet for AA** - AAEO jalapeno
At the bottom of the page is a list of about a 100 combinations it didn’t find a match for, (though I could try finding a larger word list to feed it).
riata is a word that means lariat. it’s probably from spanish, but I don’t think of it as any more spanish than “jalapeno”.
seppuku was iffy.
OK, we’ll call the AA’s done for now:

Just a note about Max’s comment:
mandelbrot = a traditional Christmas cookie made with almonds.
Riata = heard it lots of times, almost as common as the word “lasso”-- I’m puzzled that you don’t consider it a common word.
muleta = a small cloth at the end of short stick used to replace the large cape at the end of a bullfight. Hemingway, anyone?
pleiad may be more obscure, except to students of mythology or of French literature-- though it is used to designate a group, usually a group of people with a common cultural pursuit.

Interstingly, it’s also a traditional Jewish cookie.
Ditto. Riata seemed like a no-brainer to me.
And muleta was easily searchable at dictionary.com, as was pleiad.
