As far as I know, pecans aren't grown up here in the northern climes to any great extent. That's probably why no one outside of the South or Texas (not the South; it's Southwest) can pronounce the name of one of my favorite nuts.
"Hey! Want some butter pee-CAN ice cream?"
"Why, no. But I'd love a little butter pe-cahn if you find any."
Since Southerners are often taken to task for mispronouncing words (and rightly so), I always feel it's my prerogative to correct a Northerner who says "peeCAN" instead of the more luscious "pe-cahn" or (if you really want Southern-speak) "pe-cawn".
Picky? Perhaps. But "peeCAN" just lacks dignity. Yes, dignity. It strips a noble nut of its rightful place at the the center of the nut constellation. So, repeat after me: pe-cahn, pe-cahn, pe-cahn.
Very good. Now, run get me some butter pecan ice cream, please.
