There is a shop nearby where I can buy prepared dinners that can be heated and eaten - "The Pantry."
I stop in now and then to buy a meal of something I would not cook for just me or I'd be eating nothing but that for a week!
I stopped in yesterday to get an individual serving of pot roast au jus with red potato and carrots. (Yum!)
The clerk told me they had a new item and asked me is I'd be interested in a PASTE-y. I flashed on the tassles stripteasers wear then I settled down!
The new item is a Pastie. This is a half-circle of pastry (like pie crust) stuffed with meat, shredded carrot, onion, and spices and herbs with edges crimped closed.

So, do you pronounce it like the clerk - using paste-y (reminds me of glue) - or do you use the past-ie pronunciation as I've heard it from my Irish Grandmother and by Welsh folks ?
And,when you've figured that out, which is correct?
