I'm working with a French cookbook that calls for this ingredient, could be a brand name.
Kiri is a non-alcoholic soda made in Quebec. But this is the one toure probably after: creamy cheese wedges from France.
I have seen Kiri winter squash used in recipes from New Zealand (DISH magazine). Here's an article about this originally Japanese squash -- http://www.specialtyproduce.com/produce.php?item=4881
You should be able to tell from the context what the cookbook is talking about.
...and I've learned two new meanings! Thanks everyone.
From the context, it is most probably the cheese.
